You applied the new Blizzard patch.
We only support 2.3.0 atm, it takes a bit of time to update the emu to support the new patches.2.3.2 supported!Here is a way to revert back to v2.0.0
Install the
2.3.0 patch afterwards (do not connect to the blizzard realm!)
To downgrade your client, follow this:
1) Go to your World of Warcraft/Data folder
2) Delete 'patch.mpq'
3) Go back to the main World of Warcraft folder and run 'repair.exe'
4) Select 'Check files only'
5) It will take a little while to finally find patch.mpq missing. When it does it will tell you it has to fix it.
6) Once it is done, you will be back at 2.0.0.
