cindi - does it seem to download the file? But then not be able to open it?
If so, sounds like your system doesn't have the proper file association set up. It is supposed to know that when you open a document with extension of .pdf, to use Adobe Acrobat Reader to open it.
Now it is possible to directly edit your file associations, but it is a pain to explain, so I suggest basically just reinstalling AAR.
If this matches so far, I'd (without knowing which OS you have I'll be a bit general) go to Start->Settings->Control Panel and select Add/Remove Programs. Find Acrobat Reader in the list, and highlight and remove it.
Then go to the Adobe site and download the latest version of AAR. Install it. Lettuce pray /forums/images/graemlins/smile.gif
If none of this works at all try to remember that it was free advice /forums/images/graemlins/grin.gif
