Modpack error

[Nixous]

Hello!

 

I just made my first Modpack and when I try to install it for the first time and when I click "Play" it just says: http://gyazo.com/7eecb5b1fa87f4017e484914e474584e (Look at the picture)

 

What should I do? I really want to play my Modpack.

 

Edit:

I restarted the computer and now I got it to start but when I start it it says: http://gyazo.com/567d40c05f3ab0c3bb3900a2e0f3f775 (Look at the picture)
