Due to a hardware failure I was forced to do a bare metal restore of the PC. All went well, except that when I install the RAdmin server it won't let me because the key has been locked to another PC.

Factually incorrect - it's the same PC.

Logged a call with Radmin support over a week ago - disappointed to have had no response.

Any chance someone could make a request to RAdmin support to get this resolved?

Thanks.
