I downloaded the server file for tekkit, but it all in the server folder, and ran it. I did need to change the tekkit.jar name to server.jar so the server host knew which .jar i was trying to open. I think this is the reason.

Also, when I try to craft any non vanilla items, they show up in the crafting table and then disappear

I get this error but I don't know how to fix it.

Soultion: I needed to delete the old world files, change the executable to 1.1, and then restart the server. My host is global 7 hosting
