I am unable to open the Adobe reader on Desktop nor can I open it through my e-mail. The operating system that I am using is Windows XP I believe 2000. It just seems like when I try to open a document through my e-mail in PDF form I click on the attachment and the little hour glass comes on and nothing happens. Then I try to open of the program on my desktop and still the hour glass shows up but nothing happens it seems like it just hangs there.
