Help!

So im new to MOP and wow and i set my realmlist to SET realmlist "logon.warmane.com"
but i cant login to the game it asks me to convert my game to a battlenet account

if you are using the minimalistic client, the problem often stems from having a bad wtf folder or config file. Try to delete your wtf folder and relaunching the wow client and accepting the terms of service. If that doesn't work, try again or try to get a file from someone else that you trust.

Its still not fixed it stil lasked to convert my account to a battle.net

you need to download MoP from here: https://www.warmane.com/download
