Messed up Live

[CTmusic]

I was following a tutorial and changed the library path in the preference menu and now my device browser has no music. I've tried reinstalling it but the library path stays the same. I've also tried multiple diferent folders and directories in my ableton folders, but still no sound, no tutorials, no files, no nothin. Is there any way to reset ableton to its original settings? I thought reinstalling would have taken care of that.
