I get a "Not Applicable" error message within 60 seconds of opening AutoCad LT 2005. Happens EVERY time and it never happened before. I reinstalled the program. Still happens. Program closes and I have to open again, hoping I can excercise at least one command before it occurs again. Prompt tells me to tell Microsoft about the problem. Microsoft won't help since ACad isn't a microsoft program. ACAD won't help since the version is a "retired" program. Problem doesn't happen on my laptop, only the desktop. Any one out there with advice?
