Thanks for the reply.
I know this card is generally regarded as a complete flop (to put it nicely) and I've had more than my share of issues with the wifi end of things, but I must have missed the part that about not taking the latest BT drivers. I looked around here quite a bit before I installed them too. Bummer.
I am going to try uninstalling then reinstalling the previous version. I hate using System Restore...
