I previously reported a SF11 issue with not finding the desktop where music files were put. Received helpful suggestions, thanks. Turns out a Windows 10 update corrupted some system files (tech's best guess) and the fix required all third party software to be wiped from my system. I took down all license and registration information, but a visit to the MAGIX site seems to only give me the option to buy a new copy. I've reinstalled Total Recorder, which now works fine; I'm hopeful a SF 11 reinstall will do the same. Advice and suggests on how to reinstall with all registration information in hand please. Thanks in advance.
