Alright, tried to compile my test map...it worked, partly, though I get a lot of errors during compile time. Also, the gun is drawn right in front of my face, following me...

Okay, I get the following errors while compiling .bsp:

And later on...(also for light compiling and some others):

Then, when making the fastfile, I get the following errors:

I am missing the _prefabs/mp/ directory as well.

Thanks in advance!

FYI, this is on Windows XP, 32bit

You will need to run Converter at least once before actually using the various tools like Radiant, FX Editor, etc to make sure they operate properly. Try that first.
