After using Rockbox for awhile now, my Sansa c200 decided not to boot anymore

When I power on, it gets stuck showing the ROCKbox art and Boot Ver. 6.0 at the bottom.
If I try to boot to original, holding the left key while turning on, it gets stuck with the screen....

Version: 6.0

Also plugging it into my computer does not allow me to "see" it on my computer.
Whats up? any help would be appecialted.
