Seems to me there used to be a trick with these old players where you had to change a setting in what used to be called File Manager or Explorer (NOT Internet Explorer) to show “Hidden Files & Folders”.
If you have a newer computer running Windows 8 or newer, open this up (My PC), click on VIEW & make sure the Hidden Items box is checked. See if this helps.
Othewise, I think your only other option is to format & re-load.
