I have installed AutoCAD LT 2008 with stan alone license, everything works fine license was activated on the Internet.
The program works without a problem untilconnecting any USB flash drive, andthen AutoCAD shows the lack of a license.To fix this error I have to re-activate the program. I have a HP Pavilion HDX9000 computer working on Vista 64 Bit.
I installed the patch, and then AutoCAD displays the message "verifying licenses" and all work properly. When I turned on the computer the next day I received the message about the license has expired and I need a new activation code.
