Try hard resetting it by doing this:
Flip the controller over, and press the reset button. It's to the right of the middle-top screw
.
You'll need something like a paperclip, toothpick, or something similar
to push the button. Once you've reset your controller, connect it to
your PS3 with a handy USB cable, and press the PS button (just like you
did when you first got the controller). Now, it is paired again, and
you should be OK.
Best of luck!
