*Nexuiz 2.4 (GLX[?] and SDL)

I get this when I try to run Nexuiz 2.4 (GLX or SDL)
This is what I did:
Downloaded Nexuiz from Sourceforge (the default link) unzippedi it and tried running the .exe file.
Then I received the error above (the screen flickered for a second, but nothing happened. I closed all other applications, then tried again. The start screen showed up, but when I selected a map to play on, I received the same error.
I didn't have this issue with 2.3, however it ran very sluggishly. The average FPS rate (approximately 10) was worse than Crysis's average (30-45 FPS on the highest setting)
Oh, and hi, I'm new here.
