Run the EQ2MAP Updater, click on options and select your Everquest 2 path - sounds like you are were updating to the wrong one. Should be the same one you installed ProfitUI to (assuming your ProfitUI works, your /loadui comment implies it might not work - in the latter case find your correct EQ2 folder on your disk). Also make sure that ProfitUI is selected as the UI Directory (should happen automatically but can't hurt to double check).
PS:
- ProfitUI does not include EQ2MAP.
- Never use /loadui
