sansa clip locked up with blue ring and flower

Hi, I have a 4gb clip and it is stuck on the blue and ring flower display screen. I have tried the basic reset and putting it on hold and holding the center button down while hooking it up to my computer, though I don’t know what that is supposed to accomplish. i have windows 7 and also xp and have been running the clip succesfully from both.

Can anyone walk me though reformatting or recovering this clip it is very handy to have and I don’t want to give up on it. thank you

it seems pretty intent on holding to the blue ring and flower status ,  I will give your suggestions a try. thanks
