It shows that I have used 80% or so of the storage space - so I know the files are there, but every time I click on the File Page it says Page Not Found and says to click on a link to the File Page or Downloads Page... This has been going on a few days now and was not solved by clearing the cache or switching browsers.
Are you still having this problem? If you clear the browser cache and cookies do things work correctly? What happens if you try a different browser?
