Header logo messes up call to action header and community drop down

Hi guys, I love the look of this theme. I'm looking forward to getting to grips with it.

One problem at the moment though is that when I upload a logo greater than 50px high, things get a bit messed up. See image:

Don't worry about the logo positioned slightly over the edge of the header, I like that - it fits in with the theme of "MAD-ness". I've sized the logo to only over hang slightly so as not to get in the way of the community drop down, however as you can see the layout gets messed up slightly.

I tried what was suggested in this topic but it didn't seem to do anything:

Any ideas?
