I have AutoCad Mechanical 2010. It was crashing occasionally (probably my graphics card). When autocad crashes, it wants you to send the info to autodesk. I did that and it said there was a patch for my problem. After the patch installation, I do not have any mechanical commands. I did the demandload without success. I need specific instruction on what to do.Please help me.
If nothing else please tell me how to undo the patch installation.
