I don't have any group windows! :(

All the window settings, locations, and chat channels are saved in a file called server_character_eq2_uisettings.ini. Go to your Everquest II folder and find this file for your character. Temporarily move it somewhere else as a backup.

Then follow this step of the installation instructions.

Default UI settings files are included for a number of resolutions. Unless you are upgrading from a previous version of ProfitUI Reborn, first delete your {server}.{toon}_eq2_uisettings.ini file before starting the game. The game will prompt you to select an existing UI settings file. You can also manually load the default settings by typing /load_uisettings. Choose one that fits your resolution best, e.g. "1280x1024 - ProfitUI".

That should give you the normal location for the group window.

Also, there are four styles of group windows included in Profit. You can unzip any of them and overwrite your eq2ui_mainhud_groupmembers.xml file to try them out.
