Fixed! Drivers were the right place to look (although I actually updated them for something else). I upgraded to the AMD beta drivers (found here http://www.guru3d.com/files_details/amd_catalyst_13_10_beta2_(13_200_11_september_20)_download.html) and it fixed the problem.

In an attempt to start MasterCAM x6 about a week ago after not having used it for a month, the program crashed when it read "Reading key mapping file." I looked online, found others had luck with uninstalling, cleaning out .NET framework and the registry and then reinstalling, but this didn't solve the problem. Not sure what to do, I contacted eapprentice (provides online MasterCAM courses), but they were just as stumped as I was. So they gave me a link to x7. With high hopes, I cleaned out x6 and started up x7, only to encounter another crash when it reads "Running command line commands." So I go to MasterCAM support. Over the past two days I've spent a couple of hours working with one of their tech reps (who has been great), but now the both of us are stuck. So I come to all of you. Has anyone encountered a similar error or have suggestions? Things I've already tried: Uninstall reinstall Registry cleaning .NET framework cleanout and reinstall Reinstall to a new drive location Disabling all antivirus features Installing Windows updates Uninstalling most software installed since it last work (save a couple games and some Adobe software). General disk cleanup (through CCleaner and Revo Uninstaller) Thanks

I have contacted both and am continuing to work with MasterCAM support, but would appreciate any input users here have.
