Server Authentication Failed (3) message

[RX7]

Hello.

I've followed the tip of creating a account in Crysis and put to remember my password and auto. log in, before running the MWLL;

I launch the MWLL, go to Multiplayer > Internet Game and click in a listed server but I receive a "Server Authentication Failed" message, what I'm doing wrong?

TIA.

This sounds more like an issue with your Gamespy account than something specific to MWLL.  Are you able to launch vanilla Crysis and join multiplayer servers successfully?

Re-enter your CD key using the tool that comes with the DVD.

he could have a duplicate of some one else's disc and trying to run the game at the same time. if this is the case,only one will work at a time.
