License key invalid after updating to 4.2.1.2

[doris]

Hi, kinook,

I just updated my UR Pro from version 4.2.1.1 to 4.2.1.2. Now UR shows "Trial version: 45 days remaining" in the title bar. When I try to enter my license information into the Register dialogue, the following message shows up: "The name and/or key entered is not valid".
I had to reenter my license key after a few updates in the past, but I never encountered this problem.

Any help appreciated
Doris
