Problems with network-manager 0.6.6 in Ubuntu(8.04)

["Rev. Justin Brown" <justin brown1 1 gmail com>]

I am trying to connect to my school's wireless network (PEAP, MSCHAPv2, Dynamic WEP). I use Ubuntu and am trying to switch to Hardy beta. It comes with network-manager 0.6.6. However, I can no longer connect. I have tried two different ways: "Connect to another network" and "Connect to 802.1x network." They both seem to yield the same result. Are there any known regressions or should I change to a older/newer version? Whenever I edit the connections, the default always stores my password as a Private key instead of a password, which seems strange, but that also doesn't help.
Some more info:
Ubuntu Hardy beta fully updated
Kernel 2.6.24-15 #1 SMP
Intel ABG3945 running iwl3945 driver
The daemon logs repeat the same messages everytime I try to connect:
