Adobe Reader X showing Error Message: (1074724867:3), what can I do?

Does Adobe Reader X have something to do with why I can’t be able to download a pdf file from email or any website? I don’t really know why I get an error message upon downloading. The document can’t even be opened after this error. But if I try opening the pdf documents stored on my hard disk from an external device, that’s the only time it would work successfully. Can you please give me an idea on how to really fix the problem I brought up?
