crash on loading map

[lackofcreativity]

I just unzipped Nexuiz to a folder on the hard drive. Trying to play a map, single or multiplayer, will load the map, go to the terminal, and print a whole bunch of lines that are normally printed (having played Nexuiz before). When it gets to the point where the 3D rendering should be initialized, on the gl version, it freezes indefinitely. In the sdl version, it flat-out crashes to the desktop. I'm using version 2.5.1 and I have successfully used version 2.4 on the same box. I have:

WinXP Home SP3 32-bit
Celeron M 1.8 GHz
768 MB ram (128 of which are dedicated vram)
30 GB 5400 RPM 2.5 inch hard drive
15" 1024x768 screen
Radeon IGP 345M (essentially a mobile radeon 7000 series) driver version 6.13.10.6138

Like I said earlier, Nexuiz 2.4 worked under both Windows and Ubuntu at some point in the past, so it must be something with 2.5.

There is no log as the logging procedure yielded an empty file. This installation works perfectly fine on a different computer I have, so the installation itself isn't corrupted in any way. I'm not looking for speed here, as I know I'm not getting it. I just want to be able to play it, period.

Did you updating / rolling back to the previous version of drivers?

[lackofcreativity]

Yeah. I tried a few older IGP drivers as well as drivers for the desktop version of the 7000 series. The other IGP drivers didn't help the problem, and the desktop version caused severe graphical problems as Windows started up. I'm installing 2.4.2 to see if it works on this installation. The last time I played Nexuiz on this computer was on a different Windows installation.

UPDATE: 2.4.2 doesn't work either. I'm gonna try some more drivers to see if they work.
