Xbox 360 wireless controller issues

Hi, I recently bought a xbox receiver (microsoft one) for my pc and it just does not want to recognise my controller, I have updated all the drivers etc of the receiver but it just won't work, the light is constant on the receiver, but on the controller it just flashes the 4 lights constantly like its trying to connect, this is really starting to get frustrating because I bought it to play DC Universe online with, and it comes out tommorow and I am having NO luck what so ever.

he he he. its cause when ur in device manager u got to click on the xbox controller and install the driver MANUALLYY ull see it on a list. if u click just auot install driver it wont work

I just set up my receiver/controller today without a hitch.

should just need to hold the receiver button to where it's flashing. then do the same for 360.

I did do that, and it didnt dio anything.. I really am running out of ideas lol.
