I also get a direct3d error in mc13. But it's very weird, because of the following: I reloaded my laptop with a clean install. MC 12 and 13 worked before, but after the clean install MC13 will give an error in Theater View. I have tried reloading drivers, but it didn't work. The only thing different is I used nLite to create a 'slimmed down' version of XP because my laptop is 4+ years old. Could there be some component in Windows that needed to be installed?
Error is: Error starting Direct3D engine (Error creating Direct3D device)
