Well, take AutoCad 14 off the computer. You've got Civil 3d, you don't need 14 anymore. What do youj mean you don't have 14 loaded. Microsoft is NEVER wrong!! Now let's all switch over to IE7 and watch the fun!!
Actually, I suspect Microsoft got it right, and I found a bug that's existed in Autocad since R14. There's a lot of that sort of thing in Autocad, you know... Autodesk seems to feel that, as long as they file a KB article on something, they don't really need to fix it...
