Hello
I have a problem that annoys me.
 the majority of my music (cdlc P.psarc) which works very well so far has become unusable.
 I have an X that appears next to the music and I can no longer launch the music ... 
what's the problem? 
yesterday it worked very well.
 I formatted the pc so that I redo a good cleaning, I redid the manipulation to the letter to get the music (everything is fine) 
but my music downloads which worked yesterday are unusable .... help me please...

The X is when there is no arrangement for the path you are on (lead or rhythm or bass), you just need to press ctrl to switch path.
