WoW 7.3.5 Files can't start the game with Freakz launcher

[bmc444]

So yeah the title almost says it all, I have the Legion 7.3.5 data Files approx. 60 GB in my folder and tried deleting every other stuff "interface" "WTF" etc. etc.
I downloaded the Freakz Launcher copied all files and tried running. As i expected it didn't start the game, the process is running but nothing is happening and it's just stuck.
Does anyone have a solution for me or do I have to download the 7.2.5 seperatly, I'd like to avoid that since the Torrent is pretty slow. But if nothing else helps i'll have to do it.

thanks in advance!
