Once i turn it on i cant turn it off and when i go to listen to music it just goes and restarts itself

Press pause...

try this, open your side bar on your screen, press the play options on your music player on your screen if its playing to stop the music, if it isn't, then press the music player for about a seconds till you notice it changes size and drag it to your side bar. by then the music player will be gone from your screen and back to its home in the side bar.. 
regards..

Try going in itunes, right clicking on the song, and click create AAC version. The song may be in the wrong format which is why it won't finish playing it. Hope this helps!

Do NOT open the "RECORD" folder and put your music in it.
Put you music in the folder that opens. the "RECORD" folder is NOT for you to put music into. It is for you to get your .WAV recordings out of.

Ohhhhh, now you get it!!!!

USE UR IPOD!!!!!!!!!!!

"Figured it out. All user error. Re-read the manual again. Missed the obvious "Pairing HS11 and TX 10" section on page 2. Paired them properly and that solved the music listening issue. Put the HS11 itself in pairing mode (by holding down the pause/play button until the light blinked between blue and red) and was then able to pair it with my iPhone 3G. It did, however, have to actually restart the iPhone first as initial attempts didn't take me to the PIN screen. It just hung there as if it was searching. Once I restarted the phone, put the HS11 in pairing mode and then entered the PIN it worked." - found on another web site. It worked for me.

I think your music got corrupted so you have to download them again

hi, where do you get the music files?

It may be that the music has some DRM data inside such as the music sold on itunes. Get some music without any digital locks and try to play it.

Also try a ScanDisk if you had any failures in transferring files from pc to your mp3 player. Can you transfer files from pc to mp3 player withou problems?

I have a Oregon MP305 too. Mine plays music but i formatted it and now i have this problem: all that i transfer from pc is not visible inside the player browser when i disconnect it from pc. And all the files that i record with the mp305 and can listen to them on the player I can't find them when i explore the file system from the pc.

Can you make a copy of your player's file system ( the hidden directories and files ) and mail them to me?

this is my mail : csnww [at] libero.it

If you have any other questions mail me.

have your phone reprogramed maybe it has software problem. or worst hardware related problem.
