I'm having the same issue.
I am running the expanded file (decompressed) from the torrent supplied through the play now link.
I have placed WoW in programs and (x86)
I have deleted the WDB folder, every time I launch the game the folder reappears.
I have edited the config file which has the set realm, every time I launch it reverts back to blizzard logon server. The torrent did not have a realmlist.wtf file.
Copied the Config file (which is a WTF file) and renamed it realmlist.wtf, cleaned out to the contents and set it to set realmlist logon.elysium-project.org, still not working and the WDB and config files return.
I confirmed I am able to tracert out of my network but i am not able to ping the logon server.
I get the same error as poster in4abil from this thread on 10/7 @11:41PM:
