I was having the same problem after I downloaded a newer version of internet expoler. I went back to the older version and it seems to have fixed the problem. I went to start, setting, add/remove programes and found Microsoft Internet 6 and.....
highlighted it and then clicked on remove. I was then given three choices. I think it was the third one I checked and then I was asked if i wanted to go back to the older version of internet explorer and i said yes.
so far it seems to have worked.....
