Stubborn refusal! I was uploading a new video clip to my Sa51 2G MP3 Player no problems, but ehn I went to disconnect it, the message changed to do not disconnect just as I pulled the cord. Now I can't play any videos, the name of the third video clip on file is on there seven times, and when I try to play music, it gives me a loading screen that won't go past 99%. But when I rehook it up to my PC everything looks normal. WHAT'S GOING ON?!

Go ahead and open the Philips Device Manager and run the "Repair" function. Warning: this will delete all files off your mp3 player.
1) Connect GoGear to computer
2) Open Philips Device Manager (Start --> All Programs --> Philips in Windows XP if no shortcut on desktop)
3) Click on the Repair tab - see if there is a msg that says something like "to repair your player, connect GoGear to computer while holding the volume + button"
4)IMPORTANT: Disconnect the GoGear from the USB cable, turn the GoGear OFF, and then press and hold the volume + button; then, connect your GoGear to PC while still holding the volume + button (VERY IMPORTANT: this process will fix your player, but it will also delete all music and images you have stored on the GoGear) - do not let go of the Volume + button until a pop-up comes up saying that your player is being repaired

After the repair process is complete, your player should work fine - you will have to re-download all files to the GoGear.
