Mists of Pandaria client problem

Hi!So after years I decided to return to Warmane.But there is a problem I've had many times with the WTF folder thingy.It seems that the

set realmlist logon.warmane.com
set patchlist logon.warmane.com

does not work,and every time it gives me the error with the option to run in administrator and so on.Today I tried logging in without touching anything,and it worked.But the thing is that now when I run the game and try to log in it keeps telling me I need to use a blizz acc...I tried deleting the stuff in the WTF folder and replacing it with that but it didnt work either.So my question is what do I need to put in the WTF folder? :)

go here: https://www.warmane.com/download and download a new MoP client

Okay but then what do I need to do?

If you get an other problem post here again and I will tell you what to do

Tried that yesterday before that post.It did not work.

Tried it again seconds ago,gives me the same error....Gonna try to paste that stuff in the WTF folder again

Okay it worked perfectly after I put these things in the WTF folder BUT on my second run of the client it just crashed and gave me an error,something I have never seen before connected with reading.Now it continues to crash and does not want to connect me to the server at all.What should it do?
