White Screen after Mod Select

[Aurialis]

Launcher Version: 1.0.1.3

Operating System: Windows 7 64bit

Java Version: JRE7

Antivirus Program: Norton Internet Security

Description of Problem:

The Technic Launcher opens up fine, I select the Tekkit mod and log in. It seems to log in normally, but then all I get is a white screen. It never says "Mojang," it never loads into Minecraft, nothing.

I have downloaded no other mods at all, I've tried clearing the cache, reinstalling Java, deleting Meta.INF, and nuking the .techniclauncher folder and redownloading. It still brings up nothing but a white screen. My graphics drivers are up to date, I'm using the correct version of Java (64bit), and Tekkit was working for me a week ago.

Error Messages:

None. The screen stays up until I close it down manually.

Error Log:

It wouldn't let me put the whole thing here (character limit or some such), but there's the log in its entirety.

Update: I've tried downloading the .jar file and running it that way. It comes up with the launcher but tells me that it "could not connect to minecraft.net." If I then click "offline mode" it goes whitescreen again.

java.lang.RuntimeException: sidedDelegate null when attempting to getMinecraftLogger, this is generally caused by you not installing FML properly, or installing some other mod that edits Minecraft.class on top of FML such as ModLoader, do not do this. Reinstall FML properly and try again.

Try reinstalling with Norton Disabled.
