Help! RNS-E is skipping mp3 tracks?

[FourRingRider]

I purchased (2) 2gb Sandisk SD cards and loaded them full of MP3 files. Nearly all of the tracks were downloaded via Limewire. They ALL play fine on my laptop but when I put the SD cards into RNS-E (which, yes it does show ALL of the track listings on the screen) it will occassionally skip over and not allow me to select certain tracks. Any ideas?

Try renaming some of the filenames so the RNS-E recognises it easily - that has worked for me
