@Evilized - If you download the older fix
here you can install
only spells.lua and I think it will fix your problem. So you open up that zip, take out only spells.lua, and put it on your sessions\addon subfolder off your main WotN installation. If it's under steam it will be somewhere like program files, steam, steam apps, common, KB WoTN, sessions, addon.
That should stop your crashes. Then check back in a few days for bug fixes that incorporate anything the patch changed, too.
