Error in ArcBuddy

Well...that's interesting.

If I were encountering this problem, I would...
#1) Ensure that ALL versions were uninstalled
#2) Reboot the computer
#3) Re-install the software (Possibly using a different file = meaning if you used the 'Installer' for your WinXP machine, try the ZIP file instead, etc...)

...if that didn't work...I'd start looking for help on-line; this is new to me as well~!

I looked up their User Forums and did a search regarding "CAM Export". I turned up nothing that would help.
