http://www.zwsoft.com/forum/viewthread.php?tid=1278 Hey ppl, I have a bit of an issue, on certain occasions my ZWCAD2009 Pro just reverts back to a trial version. Now this is very concerning, as my dongle remains in the machine, and is never removed. As I understand, the program should be licensed as long as the dongle remains inserted, but it just kicks out. Any suggestions as to what the issue could be, your help will be appreciated.

Just pull out and plug in again? zw_admin 2009-05-14 09:54:39 http://www.zwsoft.com/forum/viewthread.php?tid=1278&pid=11306 Was the dongle light still on when you lost the license? What kind of OS you are using? Most important, you lost the license when you restarted the OS or just ZWCAD? It's a bit strange... zw_admin 2009-04-03 12:08:39
