I could already host without wormnat 2 but when the WN was playing up the other night i was trying new way to host, i download the Serverlist.htm and replace it with other one but forgot to back it up, now everytime i join a game (my hosts or someone elses) screen goes black when games starts.??

Some help please.

If you don't use WormKitDS you're saved, because you can launch W:A instead (since you can host without WK).

But if you don't only have WormNAT 2, try deleting one module at each test, or tell us your modules list.

You can also, if you didn't try yet, try to host with Wheat.

If nothing worked and you're on WKDS, you can remove WormNAT and its components, then (if you still have problems) you can reinstall W:A 3.6.31.0 beta patch, since that will remove WKDS's modifications in WA.exe.

I dont have any Hosting Problems, Just when game starts after Logo Loads screen goes black, i can still hear the sounds but just black screen. this happens online and offline. 

No, I told you to try to launch the game without WormKit, because as you said, WK is making the troubles...

Yesterday my hosting worked perfectly fine with WormNat2.
I guess its maybe some other module causing the trouble ;d

For me, since some days, BitDefender blocks wkPackets and I can't solve it...

Disable BitDefender, problem solved.
