problems with COD4 igame servers

[Sighter]

dunno if it has happened it anyone else but i added a few igames server and the other day i went on all the servers were changed to 000000.0000000:0000
i tried adding the servers again but it didnt recognize them, just had a question mark by the server eg: ? xxx.x.xxx.xxx:xxxx
any help would be great fully appreciated.

Happened to me once or twice but that was when my connection was stuffed. I think it's caused by a high ping or something along those lines.
