Forum Help with Game client

[Pdomango]

Hello.Im new in private server and i have question to ask.
I have retail copy of Base game,BC,WotLK and Cata installed on my pc.But when i log in into Warmane it start downloading game files like i dont have anything installed.Is that normal or i did something wrong in process?
By the way i sucessfully updated client to 4.3.4 with some old other private server Exe. file.
To have a better view ill copy read me file of that:

1. Copy the RAR to your World of Warcraft installation folder
2. Un-Rar it AND overwrite everything!
3. Run "WoW.exe"
4. Run "RunMe.bat"! (This deletes launcher.exe, makes WoW.mfil read-only, and sets realmlist.wtf)
5. You're now able to play on 4.3.4 server.

We do not give support to other private server clients. The easiest thing you can do now is to download this and replace what your old client with everything inside that .zip (includes realmlist).

Also, remember to log in with your username (not email).
