==== Unhandled Exception error ====

When creating a zip2go, if you get this warning before it populates, there is a solution :

{{:mc:unhandled_exception.jpg?400|}}

Go into REGEDIT and find HKEY_CURRENT_USER\SOFTWARE\CNC Software, Inc.\Mastercam [VERSIION] and delete what ever version is giving you the problem.  

{{:mc:regedit_z2g_error.jpg?800|}}

When you restart Mastercam, it will recreate this folder and correct any weirdness that caused this error.  This is a good trouble shooting method for many errors that have to do with bad files in the background.
