I've been using DoubleCad XT but there was a problem with the program and rather than try to fix it I did an uninstall an tried downloading it again. When I got to the Serial Number and Activation screen the numbers that came up were the same as what were emailed to me but when I click next I get an error message saying they're not valid. I retyped the numbers using those in the email and got the same message.
My guess is it's something to do with my 30 day XT Pro trial period having expired but all I need is the free XT. Has anyone else run into this problem?
