Hi, today I installed windows 7 on my current pc ...after big problems with the nvdia driver I installed the vista x64 diver because the 3d-preview at the N-control-centre didn't work. If I start WoW it works perfectly but when i try to start wc3 I only get a blackscreen. Under my second OS XP it works very well ;D ...the same folder error log: PHP: This application has encountered a critical error: FATAL ERROR! Program: w:\games\warcraft iii\war3.exe Exception: 0xC0000005 (ACCESS_VIOLATION) at 0023:6F0CCCA9 The instruction at '0x6F0CCCA9' referenced memory at '0x00000000'. The memory could not be 'read'.
