If you had the EC and Pinco installed before the publish where Pinco worked on the Default UI, you will have to recreate all your character profiles.
Using it without doing this part causes the game to behave in a very weird way. It is annoying, but it is how it is.
Go to Documents\EA Games\Ultima Online Stygian Abyss\User Data on Windows Explorer, make a backup of it, enter User Data, find the shard folder and delete all the files inside it.
Then log back and the EC will recreate the profile files. You will have to redo all your EC macros and set your hotbars, but it will fix all this weirdness.
Aside from that, I don't recommend Pinco for other than a few game activities such as gathering seeds, checking the pet calculator, etc. It is too damn cluttered and hinders the game performance a lot.
