It seems that this particular error comes from trying to follow the project 1999 setup over the SoF client. Problem is the getting started page provided by Project 1999 assumes you have Titanium. They do say that SoF may work to an extent, and it does but not if you follow that page completely. I was able to get on and play Project 1999 on my SoF client today, just with a ton a graphics glitches.
Heres how I was able to get on:
First off uninstall your current SoF client and delete the folder completely. Then reinstall from the disk but choose a different folder altogether. It wants to install to Sony/Everquest I changed that EQEmu, this will avoid any conflict with remaining UI files that can get left behind on the uninstall, also if your someone who still plays a live server the different directory will help avoid confusion when altering files.
Next follow the EQEmu Play Guide found here

Next from the Project 1999 Getting started guild
http://www.project1999.org/forums/showthread.php?t=2651 Download the eqchangesv9.zip. However do not send the entire package into your EQEmu folder. The 2 files that need to be changed are the spells_us.txt, and in the Resources folder the GlobalLoad.txt, leave the dbstr_us.txt alone. Also before moving dleting or overwriting ANY files copy them over to a separate folder so that if you do encounter issues you still have the original to change back.
that is the ONLY alteration I made to the client and I was able to log in create a character and enter world. Gameplay mechanics seem fine, but the textures/models are off. almost every mob in freeport appeared as a human male.
I was also able to change the login and loadscreens to the original versions following the Project 1999 guiide without an issue. Hope this helps and If I'm able to fix any of the graphics problems I will followup here.
