Download Acrobat IX Pro Trial

I'm trying to download a trial of Adobe Acrobat IX Pro. When I try to log into the download assistant I receive an error message saying there is a problem connecting with Adobe.com (Error 100). My log in information is correct because I'm logged into the Adobe site. I've restarted the download assistant three times. Reinstalled the download assistant three times, and restarted my computer. Nothing has helped. Any suggestions?
