I'm guessing that either:
- the OP has EQ2 installed in 2 different places (show hidden files and system files and look for everquest2.exe, the new streaming client likes to put it in a different folder than the CD does), or,
- the OP is mixed up between the ProfitUI interface pieces and the ProfitUI layout that it pushes forward, which stays even when you've removed the interface mods. If it's the layout that's bugging you, you need to remove the _servername_charname_uisettings.xml files so at your next login you'll have a default layout. (this will undo all your custom layout stuff, so don't do it unless you've totally ruled out #1)
If you're seeing actual ProfitUI pieces, like casting buttons on your group and raid windows, then you're looking at #1 (unless you got really confused and copied the ProfitUI files into the default folder to overwrite the games original files).
If your desktop shortcut is loading profitUI, then rt-click it, click properties, and click "open target location" in the shortcut properties, go to the ui folder in that eq2 folder, and delete that folder's profitui folder.
