My rio used to say upgrator and now its not turning on at all.

(please read everything there might be valuable information hidden somewhere Thanks!) Ok heres the scoop my Rio player worked fine for about a year or so maybe even less. Just a month ago i had it plugged into my computer and i left it there for a long time...maybe a day or so. Ok when i took it off the cord i tried to turn it on a day later and it was stuck on the RIO start-up logo. One thing i noticed was that usually when i turned my Rio on it had the logo then on the bottom in small print it would say ce2100 then it would say loading your settings..... when i tried to turn it on it only had the logo and was stuck on the logo for a long time. Then i tried holding down the On buttom multiple times and an hour later it started to turn off then turn on the the Rio logo multiple times by it self. Then after it stopped doing that it came to a blank screen with the word upgrator on the middle left side of the screen. And it was stuck like that, i couldn't turn it on or off. No matter how many times or how long i held the On button. Now when i plug my mp3 in it won't turn on at all. It won't show the connected and idle sign nothing. Just blank like a ran the battery out. Which i know i didn't because i always ran the battery out till it way empty then i would charge it so the battery shoul last longer that a little less than a year. I also tried the reset button....Nothing. I hope this helps (good luck) Marcus
