Mod packs aren't loading at all

[FR3D99]

So I'll cut straight to it.

No modpacks at all are loading. After installation, I click play, it loads, gets to 'installing minecraft assets' then just stops. 

Here is my pastebin: http://pastebin.com/9nL1DjyD

Error lines:

1. [B#301] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
2. [B#301] SLF4J: Defaulting to no-operation (NOP) logger implementation
3. [B#301] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
4. [B#301] File version.json not found in C:\Users\Matt\Documents\Technic\modpacks\tekkit\bin\modpack.jar

Please, a fix would be great. I've reinstalled technic pack and i've reinstalled tekkit classic multiple times, including computer restarts.

Do I just have to install 'version.json' myself? Where would I get it? Why isn't it installing automatically? 

And whats this 'org.slf4j.impl.StaticLoggerBinder'? 

ALL HELP IS APPRECIATED!

this is the error line that causes it to stop. How much RAM have you given to the launcher? Look it up in the Launcher Options and at the tab Java Settings
