From your post, I'm not positive exactly which part isn't working correctly for you with my UI. My guess is that your layout isn't looking like the one in my screenshot. If you look in
this thread I've posted a copy of my UI_charactername_server.ini file for people who've been running into troubles with the UI.
If my UI is working correctly, there shouldn't be anything in the error log file, so I'm guessing that the .ini file will fix the problem you're having.
The uploaded UI doesn't have the animated T. King class icons for the inventory screen, so if you want those you will want to download them and install seperately. I had to cut back some space in my zip file =)
