Nostalrius Begins - Quality wow vanilla realm (1.12)

Just when I finaly got rid of issues I had I got a problem with my PC and had to re-install the system.
My previous problem was missing patch-2mpq file in Data folder.

Now, after I copied my old client from CDs and managed to get Patch-2.MPQ file I get

"your interface files are corrupted. Please re-install the game."

Thing is, when I remove that file from Data folder, game loads just fine but when I'm in game I get dc in matter of seconds.


Server launched like month(s) ago, and I still haven't manage to spend more than 1h in game
Not saying that it's staff's fault, I'm just confused.
This client runs all existing vanilla realms even without patch2mpq file.

Maybe this will help. Folders/files under wow\data:

wow\data\interface\cinematics

only has four files and unsurprisingly they are the beginning cinematics. This shouldn't affect game performance in any way.

wow\data\interface

is empty.

wow\data

has 20 files, of which the MPQ files are important, the others aren't. You should have both patch.MPQ and patch-2.MPQ but more importantly for your problem, there should also be interface.MPQ in it.

Reinstall your wow client.
