Integrator.exe error

I installed AVG Tuneup today (free trial version) in hopes to resolve an issue that arose earlier today with a program that I have, (upon execution of that program I get "RunTime Error 91" and program wont open).  Thinking there might be a registry issue causing this, I downloaded AVG Tuneup to see if it would help.  Once AVG was downloaded, it ran through and found this and that to fix and clean up.  I went through all those motions until that was complete.  That all seemed to go just fine.  I then tried to open that program I was having trouble with (keeping my fingers crossed that what ever mysterious issue that caused it…that AVG found and fixed…), but unfortunatley I received the RTE 91, but right behind that message was another error message…AVG - integrator.exe error.  Can you tell me why I received the integrator error?
