When I tried to launch SH4 the other day, it refused to load at all - not even getting to the intro videos. I've spent quite a bit of time going through the usual procedures to no avail. Using WinDBG, and I'm no expert, it looks like the game is trying to call a nonexistent address in ntdll.dll when it loads - it looks like this may be a software issue Ubisoft needs to resolve. Willing to provide any info I can.
