Help! Help! Save me, Tech-supportman!

Tech-supportman, thank God you're here! I have serious issues with the FTB launcher!

Well, it's a long story...

It started out when I wanted to play the new direwolf20 1.6.4 pack with some of my friends. After downloading and installing the pack, the launcher would crash, and the console log shortly after. I was able to take some screenshots before it happened (actual crash logs were impossible to make, because, as I said earlier, the console log crashed with it)

The second image is fading, because the console was already crashing while taking the screenshot.

After trying some stuff that didn't work, I noticed that I didn't have windows 8.1 yet (only shaaaaame -.-).
Like an ordinary person I installed it, so what do you think?

Now the launcher won't even start anymore. It only starts the console log with lots of red lines, always the same ones:

Now, I soon noticed that this problem was quite common. I've followed certain certain troubleshooting guides (http://desk.feed-the-beast.com/index.php?/Knowledgebase/Article/View/9/0/basic-troubleshooting), reinstalled java and ftb multiple times, used a few solutions gained by searching sentences of the log on google, even tried getting the files of another computer that did work onto my laptop (oh yeah, did I mention I wanted to play on my laptop?), ran both exe and jar, tried running as administrator, set the compatibility mode (which even destroyed the console log, so I immediately rewinded that), but all without any progress. I ended up playing ftb on a shitty old computer, but I do want to play it on my laptop. Please help.

Here's some more stuff that might help reveal the problem better:
- There can't be anything wrong with Java, allright? I've downloaded it from Oracle itself (http://www.oracle.com/technetwork/java/javase/downloads/java-se-jre-7-download-432155.html).
- I run a 64x windows 8.1 OS.
- Yes, I have indeed made sure I downloaded the 64x version of Java.
- Keep in mind that if the current problem with the launcher not starting could be resolved, then STILL I may have to deal with the problem that the launcher won't start minecraft.
- Waiting, or trying again DOES NOT fix the problem.
- If I try quitting the console after it fucks up, there always remains a process of Java that can only be found with the task manager ctrl alt delete (i.e. it doesn't show up in any opened programs).
- AND ANOTHER THING: Note that other minecraft launchers do work, such as the Tekkit launcher and Minecraft itself

Your java is out of date the link you posted was for java 7 but there are versions after that. Remove any and all versions of java you have and get the one from here.

You could not have followed the basic troubleshooting guide because that guide takes you to the link for the up to date java.

@UniZero I am willing to believe you, but if that could be the case, how come I AM able to start minecraft without mods or use Tekkit? Anyways, I'll give it a shot.

[14:17:34] [INFO] LaunchFrame.main:189: Java version: 1.7.0

I know your java is the out of date because the above from within your spoiler tag indicates that you have Java 7.

If you look at line 3 from my own log here you will see that it says I have 1.7.0_40 not like your one.

Well I'll be damned, it worked! You have my thanks and my diamond

You are welcome. Have fun.
