Just got my DroidX earlier this week.
Moved all my music and custom ring tones over from my Droid1. Everything worked great. Ringtones played, music played.
Just the other day...they all stopped. I get errors when I try to play any song from my library...and the ring-tones that I had created with RingDroid (from the songs in my library) stopped working too.
"Sorry the player does not support this type of audio file."
Anyone else have this problem and/or know how to fix it?
