Andre, thanks for the fast reply, much appreciated.
To fix the problem, I know that I could just re-install the Poweramp app, but... I've done quite a lot of editing to my music library; Album Titles, Song # on the disc, year released, album artwork etc... how would I back-up all of that to ensure I wouldn't have to waste time editing all over again.
Do you know if all of that information is kept in a certain folder, and if so, where?
or if there's another app I could use to back up the current state of Poweramp to my pc and recover it later if necessary?
Would love to fix the Treble
