Never mind I fixed the problem. For everyone having the same problem as me you need to update the vanilla option in the launcher, then you can play tekkit and technic again.

I'm fairly new to Tekkit and Tekkit servers, I made one about a week ago and everything was going fine, but starting yesterday we would have huge amounts of lag and whenever there was more than one person on the server we couldn't break blocks or pick any up, then we would get kicked. This morning when I try to go on my server it said "Internal exception: java.lang.nullpointerException". I updated both my java and Technic Launcher but now when I open Tekkit it's my normal Vanilla Minecraft. Can anyone help to tell me why or how to deal with this problem? -Thanks, MrWizardMan
