What is this Gem armor you are talking about? I always thought the Quantum armor was the only end-game set. Edit: Sorry, found it.

It seems NEI is malfunctioning. Clear cache at the launcher options and login to redownload Tekkit.

Yes, thank you. The log doesnt seem to show anything, so backup your saves at '%appdata%/.techniclauncher/tekkit/saves' and then remove the '.techniclauncher' folder. Run the launcher to redownload it, then login to Tekkit.

Update your Java 7.

Do a fresh install of the server.

No.

Nothing.

There is not. Also dont sign your posts.

Its either a bug in BC or a problem with your graphics card. Try updating your graphics card drivers.

What you do is go to the Launcher Bugs section.
