If you add a mod or not does not matter. The problem is with Comodo. I had the same problem and since I had changed my antivirussoftware I can normally start the game (I use Tekkit Lite with a new mod). Try it out!

Launcher/pack Version: Launcher: 1.0.1.3/Tekkit 2.1.1 Operating System: Windows 7 64-Bit Version of Java: Java 6 Update 26 64-Bit Description of Problem: When I start Tekkit with 4GB the Game load, but when I want eg. to connect a server, I have a white-screen. But I'm already connected to the server. The I put my RAM down to 2GB and it works. Today I had to put the RAM down to 1,5GB but I have 5GB free? I do not know what to do.
