So I installed AutoCAD 2011 (Autodesk) a couple nights ago and it ran just fine for about a day. I was working in just one file the whole time and it was going great. I went to change layers (which I had done several dozen times already), suddenly the App crashed and gave no reason that I could see. I went to relaunch and I got the Splash screen and then the same App crash window popped up. Since the first crash, this is now what happens. So I've uninstalled, reinstalled (4 times). I checked my hardware to make sure that it is up to par, here's my setup: Mac mini 5,1 (required: 3,1+) 10.7.2 (required: 10.6.4+) 8GB RAM (required: 3GB+) 256GB HDD free space (required: 2.5GB+) 1920x1080 Res (required: 1280x800) Apple Wireless Keyboard and Magic Trackpad Thanks for your input!
