This kind of error usually occurs if you used a registration email different from the one used with your original license, thus creating a new account for the upgrade, rather than adding it to the existing one.

Please send us a letter to one of the following emails - support@anycount.com, support@to3000.com, support@projetex.com (depending on the product you use). Please include your original registration email address and the new one. Our support team will merge your accounts and resolve the problem.
