Rev, I'm shooting in the dark, but it sounds like you have all the files necessary to run EQ2Maps, but you neglected to edit your EQ2.ini file. This file is located in the main everquest folder. You will need it to be changed from
cl_ui_skinname default
cl_ui_subdir ui/
to
cl_ui_skinname EQ2MAP
cl_ui_subdir ui/
Another good resource is to read the installation guide here on EQ2Interface to see what files need hand modified to get mods to run for you.
How to install (faq)
Hope this fixes your problem and happy holidays.
