Hi
If you used a crack, it's almost impossible playing online, as yours is probably a not original copy of the game.
You need an original one to make it run online.
The Internet is so wide and unexplored, you thus can just try to search for a help via Google and see if there are similar cases as yours.
Keep in mind, though, that you won't find any support here for matters involving not original (therefore illegal) versions of ROTWK, neither technical nor of any other possible kind.
