My Spring crash always since some days. I don't know what it can be

From the Infolog.txt
My System:
Intel Core 2 Duo E6600 (2,4ghz, 4mb lvl.2 Cache)
2gb DDR2-553 RAM (2 chips)
EVGA GeForce 8800 GTS Superclocked Version (Omega Drivers)
abit IP-95 V1.0 Mainboard
The only thing I changed was some Graphic Options in Spring (lower), but I didn't set something off.
Can anyone help me?

My OS is Windows XP SP2, but I can change on MS Vista x64 (Multiboot).
