Can't distribute form with Acrobat.com from behind proxy

I am attempting to "automatically download and organize responses" to a form with Acrobat.com. I am working on Acrobat 9 pro on Windows 7. After putting in my Acrobat.com username and password, I get an error: cannot connect to server. I believe this is because my office is behind a web proxy. The proxy is set up as a system proxy. Is there a way to set up a proxy for Acrobat 9? I saw that the Adobe updater does not support a proxy. Any help would be appreciated.

UPDATE: Internet Explorer 8 is not able to log in to Acrobat.com. The Acrobat.com security certificate comes up as untrusted, and when I try to log in I get the following message: Acrobat.com could not contact the server to complete your action.

Since Windows 7 uses Internet Explorer settings as system settings, this explains why Acrobat cannot connect. Is this a known issue? Please advise.
