Unable to change server

Hey guys,
This is likely because the server is not live yet, but hear me out...
I have the game installed at patch 1.12.1 from playing on a private server (VanillaGaming)
I followed the instructions of creating an account on Nostalrius and changing my realmlist in the .WTF file, as required.
However, when I launch WoW.exe the server, VanillaGaming is still set.
I tried following the directions to download and replace my existing WoW.exe with a new one, downloaded from Rebirth, in case my current .exe file was corrupted.
I guess my question is, will my set server change to Nostalrius once the server goes live, or do I have a corrupted WoW.exe file?
Any thoughts are appreciated. Thanks,
