I didn't use to have any issues with this, but after switching to a new PC and upgrading to Win10 I'm having problems with the FME licence failing due to CRC-check errors. For some reason, my PC now has a different registration key (2-014-702-034) than it had a month ago (2-992-327-444) when I got my last license file.
There are no hardware changes to the PC (a HP Zbook with docking station). So what is it that can affect my reg. key this way?
