In Windows 7 Pro, after getting Error -59 when I switched usb preamps from Mbox3 to Scarlett Solo 3rd gen, I had to uninstall and reinstall SF 12 and now it asks for activation everytime it starts. Anybody got a clue how to stop this?
SF Pro or Audio Studio (AS)? Is it installed for the main user / administrator. Sorry, I am not familiar with AS or error 59. You could try uninstalling SF with a third-party uninstaller (such as (Revo Uninstall) that cleans pertinent left over data that is normally left behind by the default uninstall. Otherwise, contact the Magix Customer Service Sales Team which handles activation issues.
