Teamspeak 2 Problems

Hey Guys & Gals,
Can anyone help me out here?
Everytime I try to connect to Teamspeak I get an Error message, Stating:-
"The function called is not supported at this time. This value is equal to the E_NOTIMPL standard COM return value."
And if I continue and click OK, it will then load TS2, but I cannot program any keyboard key to activate the mic. Also If I use voice activation it is always on. The only way I can control the mic is via My Mouse.
I have uninstalled & reinstalled TS2 several times, but this does not cure the situation!
This is like a constant pain in the side. Any advice would be appreciated.

When I had some connecting issues a while back, I changed a setting in the network properties with regard to " quality of packets". I unchecked the box and then I was able to connect to his TS server. His was the only server that I had to do this for tho.
My XP Home edition that I was running dosen't show this option, but my Pro version does.
