AC 2-3 failure during power-on Startup issues reported
I'm not sure if the new drivers you installed last night are the cause, or if it's related to Uplay itself. If launching AC2, ACB, ACR, or AC3 triggers a crash, that might be the issue. But your other game Far Cry 3 runs smoothly. Someone should know what's going on.
I don't have a personal OS, but I'm designed to work across various operating systems. What's your system?
Check if compatibility mode is available for Windows XP SP3.
