I'm stumped as to how to solve the problem, let alone how it happened, though I've seen on other forums others that have the same issue. (I did a search here, but to no avail.) My screenshots are coming out black. I can see a box resembling a screenshot, but it's black. I'm not very computer savvy, so I tried reinstalling the demo . . . that didn't work. I've taken several screenshots with different game display settings, so that doesn't seem to be the problem, either. In other words, I'm stumped. Any computer prodigies out there that can help?
My system:
Windows XP Pro
Pentium 4 1.60 GHz
512 MB of RAM
ATI Radeon 9600 Pro
(monitor set to 1024 x 768, 32 bit)

Overlay is your problem not your fault nor the games fault. It's how graphics are done now. If your using the games screenshot button I couldn't tell you why it's messing up but if your using print screen or some after market screen capture they won't work.

I use Fraps it never fails me. Well almost sometimes I forget and assign a game key to the same key I assign Fraps and then I have problems.   . Anyway do a search on Google for it if your interested.

if ur using the games screenshot method and they are all black then disable antialiasing on the graphics card.
