Somehow my word documents were changed to a DOC File(doc) that opens with Internet Explorer. I can no longer open the documents. I tried opening my Passport which I use to back up these files and they were changed there also, I tried System Restore with several different restore dates with no success. The details stated System Restore did not complete successfully. An unspecified error occurred during system restore. Also I am no longer able to open Windows Media Player. I would appreciate any suggestions on how I can solve these problems. Thank you in advance for your help.
