JVM Flags: 3 total; -Xms256M -Xmx10496M -XX:permSize=128m
How much RAM does your system have? because assigning 10 GB of RAM to Java/Minecraft is more than a little excessive, especially for a 1.5.2 pack. Try lowering that to 2 GB.

Also, as Chris said, can you post your console log? It's the thing in the second window when you open the FTB Launcher.

No, That's a crash report
Ow, sorry, I didn't realise you were talking about the console log, here is a console log: http://pastebin.com/HxUkLGxs

I know there's a ton of crashes because of not giving it enough ram, and i've seen my ftb use over 13gigs (when i gave it 4g... didn't make sense) so i figured i'd just give it enough since I have 16g anyway.

But anyway, heres the console log: http://pastebin.com/HxUkLGxs

That's just because Java is like a kid in a candy store. When given more RAM than it needs, it gobbles it all up and doesn't use it properly (ie, it gets fat and bloated and can actually negatively affect your performance). 2-3 GB usually suffices in most cases, unless you're using a 64x or higher resource pack.

Have you tried to force an update on the pack yet? It looks like it's throwing that null pointer exception when trying to load ComputerCraft, and a few other mods are also throwing Java errors on loading.

I'm using a 128x texturepack, I guess giving 4-5 will be fine? (when my ftb was using 13g, i had the slider at 4, so it used a lot more as I gave. But whatever, not happening anymore now.)

And I've done a fresh install of unleashed, that didn't fix it.

Your pastebin is no longer valid. Try adding the -Xmx flag to the java parameters in advanced options.

If you want to use 4gb then add -Xmx4096

You forget that we're all just volunteers that are helping out Ashzification (who is herself a volunteer). Some times these things stump us.
