problem with bfbc2 and vent

[Touchstone]

in vent i cant get my push to talk button to work with bfbc2.
it works when bf isnt open and i assume with other games (havent tested this tho as bf is the only game ive got installed atm)
anyone got any idea why this might be happening and if i can fix it?

aaah i might try runnign it as administrator.
btw is there anyway to get win7 to just run everything as admin (i am the admin)
seems odd that i have to enable it all the time
