I discovered a strange behaving of SH5 after some while i get a black screen and shortly after i got an error table saying something about driver problem - it throws me back to windows 16 color mode and low resolution. I have the same problem when running SH4 + it mess up the ingame textures. I tried to install an older driver but didnt help. Im using Nvidia gts 260. Tried to run other games and there was no problem. Any ideas what could be wrong??

Thanks !
