dose anyone no of a setting that will fix the problem I am having with pb I can play all night on a non pb server but when I try 2 join a pb enabled server I can play 4 around 1-10  mins and hen the game freezes  

Most PB servers are now running something called an MD5 tool. The MD5 tool checks the files in your SOF2 folder against the default files for the game. If it finds any differences it will not allow you to stay in the game. On our server we are having a prob where PB kicks for file mismatches but from the players point of view they don't get kicked just lag out.
You need to contact the admin from one of the servers that you have had this problem with and see if they can tell you if there was a mismatch.

would this cause the game 2 freeze or like u said just lag out

That depends on your defenition of the word freeze. If the game just locks with no sign of life at all then the MD5 check is not your prob. I belive there is a vid card driver issue that may be cause that effect. If on the other hand your game lags (cant move but do see the "unplugged phone socket" symbol flashing in the right hand side of the screen, then my guess is that you have been kicked by PB for an MD5 mismatch.

yes it locks up no sign of life
but yet i can play 4 hours on a pb disabled server

Then I would look into the vid driver issue. I belive that is related to PB enabled servers. I think there was a PB update to fix the problem. Perhaps you should try updating PB with the web tool and try again.

Do you get a blue screen, if so let me guess your system specs...

AMD chipset like the AMD760 or 760MPX
ATI Video card

That should do it.

no blue screen no lag just game freeze.

Laptop nx7000
ati mobility radeon 9200

Possible solutions:

* Pb has two ways for checking for cheats. This can be set via the pb_system cvar. Possible options are 0 = slow or 1 = fast... check the current setting and change it to the other value to see if it helps (i did help me when i crashed a lot)
* If you are behind a router or firewall you need to open port 20112. PB uses this port for a few things and when it cant do its job you get kicked but i also read somewhere that it can cause crashes sometimes...

I assume your PB is up2date...

My computer locks up or "chugs" sometimes while I'm playing with PunkBuster Enabled, what can cause this? PunkBuster "pushes" hardware and the Windows Operating System more than most software and uses functions in the Windows API (low level functions) that aren't used by most other programs. As such, there are a few cases where using PB can actually expose flaky hardware or other situations that don't cause problems for other software. Here are a few things that have helped other users make these problems get better or go away completely: If you are running Windows NT4/2000/XP, try lowering the priority of the game process. You can do this either by opening the Task-Manager while the game is running, or launch the game by using the command "start /belownormal c:\games\sof2\sof2mp.exe" from a command prompt or in the target field of your desktop shortcut used to launch the game. Lowering the game process priority does not reduce game performance (or just very little depending on the number of programs you are running next to the game). Make sure you are using the latest version of PunkBuster (the latest version is always on our Download page) - also this link may help manually update your PB to the latest version when necessary From the game's main screen, press the tilde key (the ~ key) to bring down the console and enter the following line (without the quotes): "/pb_system 1". Never close other programs from your Windows Task Manager before playing the game, either leave them running or close them through the proper interface - killing a process doesn't always work completely even if it stops showing in the Task Manager and renegade threads seem to conflict with PB more than other programs that may be running in memory. There is a free utility that some players use called EndItAll to close all extra programs before they play to avoid software conflicts, crashes and lockups. You can get it from here. Check the add/remove programs list in your Control Panel and uninstall any programs that you don't use or that you don't know what they are. One program that seems to conflict with PB more than others is Norton Anti-Virus. If you have it installed, try uninstalling it to see if the lockups go away. Some players have reported that when this is the culprit, they can reinstall Norton Anti-Virus and the lockups don't come back. Other background programs that seem to conflict with PB for some users are Sound Blaster Live software and helper programs that come with video cards (especially ATI keyboard shortcut programs). Some players discovered that they had a computer virus and that the lockups vanished after it was fully removed. Experiment with the pb_sleep setting ... try setting it to 20, 250, or 500 to see if that affects your game performance. A few players have reported that all the problems go away when they "tweak" this setting. In extreme cases, a few users have reported that replacing their RAM (memory) or video/sound cards fixed the problem.
