Hello,
My serial number is invalid. I'ts an upgrade version, form 11 to X7, and it worked to me until the last WIN re-installation.
The software is registered in corel.com - with the serial number- but impossible to use in the real life.
I try to installation from the original DVD / latest downloadable version of Corel X7, but the result is same: Invalid serial number".
Is any place in corel.com where I can check or renew my serial?
