Spring RTS Engine

Hey folks,
i downloaded Spring and the last stable CA mod release.
After starting a single-player game in spring (no matter whether through the MP client or direct via "Test Spring") i can play (although it laggs a bit) for around 1-3 minutes. Then spring freezes, in some cases there is a Application Box saying spring crashed.
Sometimes it freezes few seconds and then my pc suddenly restarts.
infolog attached.
i know my graphic sux

this usually means your graphics drivers are too old. update them.

well, still not works.
i now tried it on my other pc, didn't work, and so i updated its graphic drivers, too.
still doesnt work, unfortunately.
can anyone help?
(already tried windowed mode)
infolog attached.
thanks for help

Crash points to KAIK. Remove the AI and it may work better.

alright with RAI it works!
thx guys, and very great game! somehow better than any commercial stuff.
