Hmm... just to make sure you're connecting to the right thing, your eqhost.txt (C:\...\Everquest\eqhost.txt) file should say this:
Code:
[LoginServer]
Host=eqemulator.net:5998
and nothing else.
Moving those files lets you enter those zones. There's an incompatibility between the installed versions and the playable versions (which are .s3d files). If you don't move them out of your directory, you'll zone in and just be falling through blackness.
