Error Message -- Guitar Rig Related?

[emelare]

I'm getting an error message and I believe it may be related to Guitar Rig. I'm running the Guitar Rig plug-in in a session. I first encountered the problem after I recorded a track with Guitar Rig. I then printed the recorded track to another track to conserve cpu power. When I went to delete the original track with Guitar Rig, I received an error message. Also, when I tried to simply remove the plug-in from the original track I received the message. When I simply go to close the entire session, the error message comes up. When I re-open the sesssion, my work is, however, saved. The error message reads as follows:

Pro Tools Application has encountered a problem and needs to close.

Thanks for your help. Michael
