Serial number does not work

[completedegen]

Yesterday, I paid for an upgrade to hold 'em + omaha manager and received a serial number. When I try to register that serial number, the software tells me it is invalid, or has not been used.

1) Help > Reset License.
2) Close HM, restart HM, click Register, and finish the registration process.
3) If you have any problems, please try using our registration system to reset your license. http://www.holdemmanager.net/Registration/
4) If you have any problems beyond that (such as a holdem and omaha license that need to be merged), please email the details to sales@holdemmanager.net and they should be able to kill/reset your codes.
