Honestly Fenril, I dont know either. I dont know enough about coding to be able to tell anyone what the particular line or whatever is wrong. But what I see...Something of the UI stayed, or altered the profile, and wasnt "removed" when I turned off the UI from the addon screen.

I admit when I set up the SSD for the first time, I copied the WTF and Interface folders from the previous HDD, and pasted them into the new drive. I was able to keep my gatherer info, login settings etc.

I really dont know.
