Sorry I had not read anything about re-installing the Operating System. At this point every program appears to be running smoothly and always has. I rather not re-install the Operating System. For one rather embarrassing reason I probably don't even know how to re-install it since no manufacturer ever issues discs any longer. I am exhausted with this AutoCAD licensing issue and after reading many other blogs I am not in the same boat.
I appreciate the efforts you made to try to get the software to work. In the end it just did not like my year old Windows 7 Dell computer.
