So many people have asked this, but still we have had no replies. All players but the host get kicked out and they get a "Server Authentication Failure". Any help/fix would be greatly appreciated

My last post didn't get replied to so I'll try again. Basically me and my friends  play WAW custom zombies over Tunngle Lan on a cracked version of the game. However we can't play together after installing T4M mod because either a Create Online Profile pops up or Server Authentication Failure after trying to load a map. One moderator suggested I put my texture quality on low but that didn't work so we are still trying to figure this out. Any help would be appreciated, thank you.

okay, i tried it with my friend and it didnt work, he got kicked out and he got a message saying "create online profile"

Alright, I'll try it with a friend as soon as I get a chance, thanks

I've tried to play this one mod, "Ragnarok", and it requires T4M and so I have downloaded it and I can run the map solo but if I try to host a LAN server over tunngle and have my friends join, the others will get kicked as soon as I'm ready. We can play other maps without T4M together, so we can't figure out what the problem is. Any help would be appreciated. I'm also running a cracked version of World at War and with tunngle we can play together but with T4M also installed it won't work.
