Computer is an ASUS (I can't find out what model) but I'm running Windows 10 Home Version 1607 and the Studio One v184.108.40.206360 on Windows 64-bit, Audio Interface is Windows Audio.
Basically, my version was running totally fine and I downloaded another program called "REAPER" for direct mp3 file adding and chopping, after a while I came back to use Studio One again and all my Impact and Presence instruments were gone. I haven't been able to locate them anywhere on my computer either.
So in short, I messed up big time. How can I either re-download my instrument sets or (preferably) completely restore my version to how it was when I first got it?
