i dont think so. but if it says certain files are missing, it sounds like your cards corrupted your files. simple solution : copy as much as possible off the card(you cant copy corrupted files i dont think - you'll get an error) then format your card and replace everything. Then download any files that were corrupted so wouldnt copy. For example, you should probably redownload VGH. Once you have your card fully set up with all games working etc. make a backup for when it happens again(which it probably will somewhere down the line)
So basically, format your card and redownload VGH. Hope that works.
