Firmware Update caused problems

I followed the instructions and updated the firmware on my sansa fuze+ and now i can only go to the music menu. Everytime i try to go to the videos menu, it resets itself. I select english, then north america, then try to go to the videos menu, and the screen goes black and the power on screen comes up and it brings me back to where i select english. I have tried holding the power button down for 15 seconds and that doesnt work. I do not have any mp4 videos on there, as i know that may have been part of the problem. Does anyone else have this problem and know how to fix it?

The same thing happened to me. I discovered there was a video file that was causing mine to keep resetting. I removed the episode and it plays fine.
