Just as a preface to my plea, I know the first thing anyone will say is that I must have some file in the wrong place, but I have been using custom UIs for years and know where everything goes. I have verified numerous times that everything is in the right place. I wish my problem were that simple

I have run out of ideas, so i'm hoping someone here can help me figure out what to do.
Long story short, my UI was working perfectly until I formatted my computer and reinstalled EQ2. I backed up my UI folder, eq2.ini file, uisettings, etc and copied everything back over into the right place after having reinstalled EQ2.
When I logged into EQ2 afterwards for the first time, it worked perfectly. My old UI showed up fine and all my old settings were restored. However, once I logged out and back in everything was reset. UI, resolution, texture settings, etc. For the life of me, I cannot figure out what is causing this. I assumed that one of my files was somehow corrupted in the backup process, so I deleted all of my ini files and ProfitUI folder and installed a fresh version. The only problem is, EQ2 still doesn't want to load it. When I login everything is still default. When I try to use the /loadui command, Profit does not even show up in the list. It is like it is not even seeing the ProfitUI folder inside of my UI directory, even though my EQ2.ini file is telling the client to use it.
Out of frustration, I completely deleted the UI folder and all of the .ini files inside of EverQuestII and run a complete scan so that the patcher would revert all of my files to a fresh install. I then downloaded another copy of ProfitUI and followed the installation instructions, but I am STILL experiencing the same problem.
