Can you not connect to the server?
There are a few things that you can do.
1. Make sure you have autodownloading off
2. Make sure you have the map that the server is on, in your BaseEF Folder and RPG-X Folder
3. Open up the console (by pressing ` (the button next to 1)) and scroll up untill you find,
########Error###########
4. Report it to a server admin
