Problems with punkbuster on battlefield 2

[Matt789]

Just wondering if anyone is having problems with Punkbuster in Battlefield 2. I am NOT running the 1.01 patch, and i am getting a WARNING that my punkbuster files are not up to date, this happens mostly on every server i go on. I thought Punkbuster is supposed to update it automatically but who knows whats happing it could be because that i dont have the v. 1.01 patch installed, i even tried updating the files manually but that still didnt help. If anyone is having the same problems i am, please respond if you have any information!!
