I registered DOpus a while back but have now lost the e-mail with my registartion code.
I can't use the Technical Support form to get help with this as my "evlauation" period has ended and I can't enter my registration code to get the support I qualify for as I have lost my code. Can anyone tell me how I solve this?
If you know your email address and registration code then you can access the web-based licence manager and retrieve the registration certificate, change the email address, etc.:
(If you have Opus installed then you can get your registration code from Help -> Licence Manager. That isn't the full licence, so you can't use it to install Opus, but it may help GPSoftware identify you.)
