I was trying to download the beginners guide. But when I tried to open it, I received the message "Navigation page has been deleted" - or something like that. Then I was playing around with Recuva just to see what it might be able to do for me in case of an emergency. Well, I picked some recently deleted files (.pdf and .jpeg) that were marked as "Excellent". Could recover them alright - the .pdf looked like a normal Adobe file and the .jpeg looked like a generic picture. But when I was trying to open them with the respective programs, those programs could not deal with the filetype (supposedly corrupted). Is there some pre- or post-processing I have to do or am I missing something?
