Related to my last post: My work computer (where WoW 4.x runs without issue): OS: Ubuntu 10.04 Kernel: 2.6.32-25-generic #44-Ubuntu SMP Video: ATI (using fglrx driver) Wine: wine-1.1.42 My home computer (where WoW 4.x has the "internal error"): OS: Ubuntu 10.10 Kernel: 2.6.35-22-generic #34-Ubuntu SMP Video: nVidia (using nvidia driver) Wine: wine-1.2 Before I upgraded my home computer to 10.10, WoW still wasn't running, it was just giving different errors (like the one in the screenshot posted above).
