WD2GO not playing music files on Android Razor Maxx

I have a Razor Maxx with WD2Go installed.

My issue i can play a music file if there are a limited(ie25) number of music files in the shared music folder but not if there are many(ie 500) music files.

Thank you in advance for any help.

Do you get any error messages when you cannot play the file?

Thx for your reply.

No error messages. When i press play it looks like it is going to play but stops and never plays.
