MTA Client Verification failed, help pls

[_Andrea_]

Whenever I try to join two of the RPG svs I play in, it takes forever to down and for me to get to the login panel, and when i am able to log in i have really bad lag and i get network trouble, and sometimes my mta crashes and it tells me "MTA Client Verification failed" and it only happens when I join one of the two RPG svs, the rest of the svs I play in are fine and im able to play normally, Someone please help
