Client freezes when I try to log in

I used to have electric sheep working just fine on this computer. I installed 2.7b16 at the time. Recently I wiped my hard drive and installed Windows 7, and when I tried to install the client again, I could no longer log in. It would give me a "failed" error the first time (despite the password being correct) and then when I tried again the second time, it locked up entirely. I had to end the process. Thing is, I reinstalled XP just a few days ago. And now I'm getting the exact same problem despite it having previously worked on XP just fine. I've tried both my 2.7b16 install that I knew worked at first and the newer b17, same issue. I've also tried it with two accounts - same problem. Anyone know what's up?
