EDIT: IT WON"T LET ME GO ON ANY SERVER!

There is an edit button for a reason. Also, you need to downgrade to Java 6 as Mac, as of mountain lion, no longer has Java support.

Is that the problem? Because I can play single player.

It may well not be, but it wouldn't hurt. What version Tekkit server are you running because 3.1.3 is the latest and if you made a server for 3.1.3 and you are using 3.1.2 as your client, you will get some missing mods from the update.

How do you know that my client is 3.1.2?

I downloaded one again today. Same problem. When I logged in it asked me if I wanted to update. I said yes. Would that be the problem?

Never mind not the problem. CAN SOMEONE HELP!!!

How do you know that my client is 3.1.2?

In the launcher window: click Options, Manual Build Selection. Find 3.1.3, update, and try logging in. If it lets you, you downloaded the 3.1.3 server instead of 3.1.2, which is available on the Tekkit page of www.technicpack.net under the Tekkit tab at the bottom (Previous Server Versions). Based on the IC2 version it says you're missing, I'm guessing that's what happened.
