The best thing you could do right now is go back through the setup following the wiki and make sure you have all the directories right. If it's failing to open the config file and the file is properly named and in the eqemu folder everything should be fine... unless it's a permissions thing. You're not trying to run this on Vista are you?
The line in the config file that says "Only change this if you really think you need to" should be renamed to "Never change this" It really means what it says, and is better removed than changed.
I don't run minilogin myself, but don't you need to point it to the world address in the loginserver.ini?
Code:
#worldaddress=Your IP Address here
