Raidcall overlay

Hello guys i am a stuck bit here i would like some help from people that know abut simple programming since i only have some basic exp , back on Cataclysam if you where using raidcall if you press Shift tab (Default Bind) it will open overlay ingame so you can see who is talking without alt tabing all the time . Now problems lies here raidcall no longer supports WoW from what i have found in raidcall files and config file there is alot of games but not wow . Does anyone know how to enable that because what ever i tried changing files it just wont save my settings , i even took fullcontroll over the file. Help please :)
