Bd Is Blocking My Wifi!

This morning I upgraded my Lenovo T61 from BD IS 2011 to 2012. Since then it won't let me connct to my WIFI router. I get an error message saying "There are problems connecting to TPM on the computer. The connection is possibly being blocked by an anti-virus or firewall program."

The computer connects via Lenovos "Access Connections", and I'm fairly sure BD is blocking it, as it worked fine before, but not now.

Help!
