Keyboard keys stuck when playing BF2

[mrserv0n]

I just bought a Kensington wireless keyboard, and when I play Battlefield 2 my keys get stuck (not physically) and my guy just keeps walking in one direction, I have tried turning off stick keys and all that and went into keyboard through control panel and messed with the delay times and such. whats the problem? It was working fine for a week now its doing it constantly

Not sure on this one but you could check and see if there would be anything interfearing (sp?) with the signal going from the wireless keyboard, to it's reciever.
