So I have gone into the system, done the multiplayer key changer, entered the keys assigned to me under my in browser game, now whenever I try to connect to the multiplayer, it continues to say my CD key is not assigned to my indvidual game.

I have checked the nwncdkey.ini and it appears to be valid

EDIT

Solved, the problem stems that the cdkey file is not also saved in your documents file, so I had to manually transfer that over. So while in the drive/where the game is installed is alright, the program needs to be updated to include it in two places instead of just one
