Launcher seems to be broken. Nothing on it loads up properly, I can't launch, and forcing an update results in an error. First time ever using FTB.

I looked up the error, and it seems these errors have something to do with having multiple versions of Java. I uninstalled and wiped every version of Java, and re-installed one copy from the Java website.

When I click launch, I get this error in the console:
Code: 
Unhandled exception in Thread[AWT-EventQueue-0,6,main]: java.lang.ArrayIndexOutOfBoundsException: -1

If I hit download server, I get the same error, and all I see on the left half of the launcher is "Please wait while mods are being loaded...", they never load.

Launching log, Launcher Version 1.3.2 :

I also just found out it didn't re-install the 64-bit version of Java. I did that and now my launcher spits this out when I open it:

I then tried running the launcher as an admin, and now my startup log looks like this:

Still getting the
Unhandled exception in Thread[AWT-EventQueue-0,6,main]: java.lang.ArrayIndexOutOfBoundsException: -1 error.

If this launcher is THAT finicky with Java versions, I can't see how anyone could ever start a community and tell every one of their players how to solve every one of these problems. I get these errors on the exe launcher and the jar launcher.

Windows 8 Pro 64-bit.

That error can appear by having multiple java versions. Try having just the 64 bit version. If you still get an error then post a fresh log to pastebin and link it here.

I suspect that the check regarding java versions was added because all but one of the 1.6 packs require 64 bit java and the only one for 32 bit systems is FTB Lite 2.

Also, Make sure to run FTB in Administration mode, And try changing your server download location to Nuttingham, And if that does not work, Try the other servers, Remember to close your FTB and reopen it each time you change your server download location.

BACK UP YOUR SAVE FILES

Go into your Roaming folder and delete the ftblauncher folder.

That usually fixes this issue.
