ummm, in my knowledge
that is impossible so maybe
just maybe, it worked once and it broked because it is not possible
try takin out the batteries then hit the red sync button on the wii then the red sync button on the wii mote in the battery compartment that should work ive never heard of it being synced to a computer b4 but hopefully that will fix it for u
First off mdnpascual is wrong it is not impossible for your wiimote to be connected to the pc as you saw and no it will not break it. Secondly, what naotax2 said should work if not contact someone here: and they should be able to help.
just take the battery bit out and the red sync button should be there and then on your wii with the compartment for the SD card there should be a red sync button in there to! press them together at the same time and hopefully it should work!
hope it helps!
