I'm posting this because this tripped me up when I first upgraded to the new Pinco's UI, and my guess is it's causing problems for a lot of people. Pinco's UI now auto cleans your character files, so you don't need to delete your character files, but there are two locations that you do need to delete before you install the new Pinco's UI for the first time. 1. [Ultima Online Enhanced game folder]\UserInterface\Pinco's UI 2. [My Documents]\EA Games\Ultima Online Stygian Abyss\User Data Inside that folder delete all the folders except the folders with your account name. Then delete the Pinco's UI folder, then reinstall. Then you unzip the Pinco's UI install package into your Ultima Online Enhanced game folder, start up "UI Patcher.exe", and if you get the infamous "Unhandled Exception" error, start up the "File Shifter.exe" instead, and that should fix that problem for you. After that you can make a shortcut to "UI Patcher.exe" and start the game that way from then on.
