Cisco Clean Access Communication Problems

Hey guys. I just got back to my college dorm room yesterday and I can't seem to connect to the campus's wired Clean Access. I have installed the newest version and I keep getting an error. (see attachment.)

There is one more error that happens before I get to the authentication page. It says something along the lines of " this certificate was signed by an untrusted user. Proceed anyway?"

I'm not sure if anyone is familiar with this problem, but I was wondering if anyone had any ideas to what this problem is or how to fix it? I'm running 10.5.8 on a Blackbook.

Thanks for the help.
