I've been trying to get tekkit to work on my bukkit server for some time now. I downloaded the launcher and everything works fine in single player. But when i try to put an tekkit item in my hot bar from the item menu, i get kicked from my server and i get this message on the pail server manager.

What do i need to do to get the server running so i can use tekkit with my friends?

sounds like you're trying to add tekkit to an existing server. that is probably not going to work. grab the tekkit server from the home page and start with a fresh tekkit server. once you are able to log in to that (should not be hard) you can try to start adding in whatever plugins you had on your old server.

Fresh tekkit server pack, edit the server.properaties, copy your map over, copy over any plugin configs and make sure to download the plugin version compatible with Bukkit 1.1 R4 or lower.
