I was on a frequently used site and it was recommended to download Adobe to view some PDF files. After downloading Adobe I made it the default viewer and now can not view the PDF files that I used to see before doing this. I can view saved PDF files but not PDF files from this site any more. I may have also deleted a file I needed to view these. Trash bin is empty so I can't check. Is there some kind of repair application that will put these files back on the OS? i have Lepoard. Thanks for any replies.
