AirPort won't switch back on!

[Nerdowl]

I switched my AirPort card off earlier, when I tried to turn it back on nothing happens.

Have tried restarting but that didn't help.

AirPort card still works in Vista though (running in bootcamp)

Any ideas?

I'm using MacBook 2.0GHZ core duo with MAC OS Leopard.

Any ideas?

Thanks.

Problem solved by re-installing leopard.
