COD 4 won't show any servers! HELP!

[prappatherappa]

Hello,

I have been playing COD 4 on my iMac for a while (I didn't buy it on the MAS), and for some reason, it no longer shows a list of multiplayer servers I can join. I try to refresh the list but nothing works. Is this happening to anyone else?

Thanks in advance.
