Stuck on Connecting while logging in, what could be wrong?

Hey guys, good evening

So basically I have come back after 3 months and I downloaded Mists

I removed read only from WoW shortcut properties, started up and everything was fine.
I typed in my account name and password, it basically stays on connecting for entire minutes, during rare occasions it comes up with a message that I need to log in from a Bnet account/mail

It was never like this before when I used to log in, I even tried the normal "Mustoo" as account name and even my gmail, and even Mustoo94 but nothing seemed to happen at all.

Is anyone familiar with this, please help out :)

This is how the Config.wtf file looks like, opened through notepad.

SET locale "enUS"
SET installLocale "enUS"
SET hwDetect "0"
SET videoOptionsVersion "5"
SET gxApi "D3D11"
SET gxWindow "0"
SET gxMaximize "0"
SET maxAnimThreads "6"
SET readTOS "1"
SET lastReadTOS "50408"
SET readEULA "1"
SET lastReadEULA "50408"
SET Sound_MusicVolume "0.40000000596046"
SET Sound_AmbienceVolume "0.60000002384186"
SET farclip "1000"
SET particleDensity "80"
SET waterDetail "2"
SET rippleDetail "1"
SET reflectionMode "0"
SET sunShafts "2"
SET groundEffectDensity "80"
SET groundEffectDist "200"
SET environmentDetail "125"
SET projectedTextures "1"
SET shadowMode "2"
SET shadowTextureSize "2048"
SET SSAO "1"
SET SSAOBlur "1"
SET textureFilteringMode "4"
SET terrainLodDist "500"
SET wmoLodDist "500"
SET componentTextureLevel "0"

I got into the game now, with other problems.

I cleared the whole Config.wtf file and wrote instead

SET locale "enGB"
SET installLocale "enGB"
SET realmlist "logon.warmane.ru"

I am in the game now, I received a lot of errors for any action I took like "Ignore" or "Disable" if I press Esc button, guild tab etc

I deleted WTF folder, cache

I still have those problems and I ENDED up losing my keybinds/macros in the process

you didnt back up files? and then emptied your recycle bin as well before checking?

all you needed to do was add the realmlist lines

SET realmlist "logon.warmane.com"
SET patchlist "logon.warmane.com"
