Windows .exe FTB wont load modpacks at all

[Addylad]

So basically i had FTB working fine with a world on Direwolf 20s modpack and as usual i updated the modpack as and when it needed. Recently though FTB has started to fail on me and after extensive internet searches I for the life of me cannot figure out why.
Firstly I like many others dont have a clue what half of the FTB console says so anyone who can decipher it and let me know how to fix it so that i can load into Minecraft and actually play it would be much appreciated.

Below Is the pastebin file of what is going on.

*Side note this is occuring after a completely new fresh install so all other previous FTB files have been removed from my pc.
**If any pc Specs are needed other than the fact i have 8gb of ram then ill gladly tell you them.
