Clip+ problem need help

Im having huge issues with my clip+
when i turn it on with usb connection it says file not found and turns off.
when i connect a usb to it it loads up sansa then the icon of the computer and clip appears,says writing briefly,then connected.however my computer doesn’t recognise this connection,and there is no other externanal drive in view.

also i tried it under mtp and msc and seems not to make a difference.
when i try boot it up it says file not found but still had the rockbox logo,then turns off

is there anyway to just wipe whats on it?

you can try pressing the HOME Button while you turn the clip+ on and that should load the clip+ os.  if it does make sure the usb on the clip is set to msc then try the sansa updater from our PC  and see if it will install the original firmware and you will need to remove the .Rockbox folder from your clip+ as well that will bring it back to factory condition if it works.  if it didnt work bringing up the clip+ os then you could still try the sansa updater and hope it works.  I was able to uninstall rockbox that way and get it back to the stock OS,  I didnt have time to figure it out Rockbox and it kept freezing on my so I decideed to stick with the original
