Conquest of the Horde

Right...so. I installed TRP2. I got rid of TRP. I deleted my cache, and as soon as I log in I get an "error occurred while loading, addon won't work correctly" sort of message. The right click works on the icon on the minimap and the right half of the float-y menu works, but nothing else does. I tried installing older versions, same exact error. The only other addon I have is GHI.

*cries* I am such a nub when it comes to these things. Someone help? D:

I'm not sure, but tell me the contents of your addons folder.
