Code:
[LoginServer]
Host=eqemulator.net:5998
That is the one you need to use, not any of the others you posted. Also, you mentioned trying it before and after patching, and just so you know, EQEmu will probably not work now since you patched. Even patching for a second will break it. You need to run a fresh install of EQ directly from the disks from either Titanium or SoF.
Also, for your file issue, you should be able to right click on your desktop and create a new .txt file there. Then, name it "eqhost.txt" and put the required info in it. Then, simply copy that file to your EQ folder and overwrite the existing one. That should let you run just fine. Again, before this, you are almost certainly going to need to uninstall EQ and delete the whole folder it was installed in and then reinstall it fresh from the disks.
