Figured out what the problem was. When I was still waiting on confirmation to get into the nUI download section I had another UI installed. Unfortunately after uninstalling it, apparently it saved some variables and other things in practically every folder I had for WoW and I didn't know about the files. After finding them all and uninstalling everything and only putting nUI (plus the stone skin, info panel and minimap) and only putting on FuBar (plus the plug-ins I use for it) and everything works just fine now. Including the vehicle buttons
I was able to charge at stuff in the Tournament area without having to click on the buttons
