[Radar won't work please help]

Thanks for the help, i'll give it a go.

[Radar won't work please help]

I downloaded Version 3.22 of FSUIPC I followed the instructions but the radar won't work. I have clicked modual in the corner on fs9 and it says it is unregistered but in the user guide it says it should still work with less benefits. I have a few aircraft with radar and would love to go intercepting airliners but the radar just shows blank :( I have searched the forum but could not find any thing. Please help.
