I have just purchased Audio Studio 10 a physical copy, after trying a trial package from MAGIX. When I input the serial number I am presented with the registration screen again with the error Your Sound Forge Studio Trial has expired and asking me to enter the serial number and click submit (image below)I get the same error with my disk and also an official download from MAGIX using the serial number provided with the software. I have uninstalled the original trial package, and even tried cleaning my registry, Could there be a hidden file somewhere. I had no issues with the trial version. Any suggestions will be appreciated. I am running Windows 10 and had a major PC upgrade in December 2020. Many Thanks
