Topic: Controller pairing problem

Hello,
I bought a series x controller with the wireless adapter to use it on my PC. It paired up on the first try, everything worked fine. A few days later, I paired the controller to my iPad, since then I can't pair it to my PC.
Is it possible to use the wireless controller with several devices?
How can I force the pairing to the PC?

The receiver does not emit any light, should it not light up?
Maybe it is out of order.
