Highly needed Crimson Skies multiplayer able crack

[Shaker]

i can't play crimson skies as multiplayer game in the MSN Zone. i applied the offical 1.02 patch, which is needed, and unwrapped the icd-file to exe-file, the game works, but multiplayer won't.
Perhaps a good cracker is able to crack it, I would be very thankful!
