Incorrect map info error

Hi all,

Sometimes when I'm playing CF I get an error saying this: "Disconnected due tu incorrect map info" and then it disconnects me from crossfire.

Here is the link of the picture: http://i41.tinypic.com/33bhheb.jpg

Please don't say "try to re-instal", I've done it like 3 times and still have the same error. Note that it doesn't appear at the begining or the end of the game, it only pops out of no where and that I get this error like 2/3 of the times.

Sorry for my english in french...

Help!
