Wow...that's a new one stopping at Line 8 for no apparent reason. Might be a good Idea to "Backup Up" the Machine Parameters and 50MU's Source/Options/etc Program before pulling any Cards or Chips would be the first thing to do if, you have not already. Those are different than your Part Programs. Don't want to lose that information. Type "PLC" to access at cold start Screen.
Dynapath is still in business if that helps you.
