I just tried to open an AutoCAD file it opened fine then 45 seconds later I get an "AutoCAD LT Error Aborting"
"INTERNAL ERROR: !U:\global\src\corecad\coresrc\laymgr.cpp@955: eLock VIolation"
Having Saved the file to the desktop the error message became:
Fatal Error: Unhandled Access Violation Reading 0x0040 Exception at 6bf87eh
What does this mean and how do I overcome it to be able to view the file?
