I have been recieving this fatal error for a few months. No computer changes or software changes... The drawings are files I've worked with for years. I've tried the disable signature icons and it has not helped. this is getting very frustrating to deal with... it only happens when I try to open a file and does not always do it... here is a screen shot of the error.
Also, I have sent about 50 of the autocad error reports and have had no help!
I can not trigger the crash... It's seems to be random. Opening a new drawing or opening an existing drawing gives the error. sometimes I can open drawings most of the day or start a new drawing most of the day then i might get the error 10 or 12 times in a row...
The screen capture you show indicates you are using AutoCAD Mechanical - not Mechanical Desktop (where you have posted this question). You are more likely to get an appropriate response on the AutoCAD Mechanical forum.
