Question

Studio One 4.6.  On boot up, the program that has been working daily for the last 2 years asked me if I agreed to the terms of use, as if I were a first time log in. Then I noticed that the “recent song” list was gone. Blank, except for 5 songs I worked on 2 years ago.  What has happened?  And there are glitches in the song playback- little stutters that are not there when I hear it again.

Answer 1

Sounds like you got your settings folder wiped out.  Or at least the file that retains your "recent projects".

What exactly are you asking?
