Making a CSP Error

[Crash]

I followed

<a href="http://www.youtube.com/watch?v=cLeVyjb7AFo" target="_blank" class="aeva_link bbc_link new_win">http://www.youtube.com/watch?v=cLeVyjb7AFo</a>

That tutorial exactly and when I ran step2_create I got this:

'ERROR: ike is too big
You should reduce the amount of colours in modified portraits.'

Help?
