Yes, I am using minilogin. I'll try doing what you say, dumping the DB then re-sourcing it without my addons, then see if it works. I'll also try and get a copy of the exact error message it gives (if it doesn't work).
I'm still enjoying playing MW and NWN, however I thought I'd try out EQ/EQEmu again. I still like EQ's unique style, with each race having its own city and lands, even if the setting is unoriginal. I'd really like the fourth Elder Scrolls game (if there is one) to include the whole of Tamriel, like the original ES1 "Arena" - obviously it'd have to be scaled down a lot to be manageable design/creation-wise (even if PCs have the memory for it), but it'd be great to be able to travel between distinct lands with their own people, language, architecture, unique items etc.
I have my own website now at
http://www.edwardpinniger.bctalk.net which is still under construction, but I plan to have an EQEmu page there soon where I can put my DB addons for download.
