Can you help me with my footer?

[Anatchim]

Hi there,

I am quite new to this... I do have some knowledge of plain html and css.

I have installed Prestashop 2 days ago, and have been configuring it since then, based on the Classic Theme...  It is at http://www.nadir.pt/presta17/index.php 

I would like to have extra links to cms pages on my footer, but whenever I add a new block, instead of going to the right of existing columns (even though there appears to exists space), it goes to the bottom... I attach an image for better understanding.

I have:

Our Products / Our Company / Your Account / Store Information

I would like to have:

Our Products / Our Company / New Column / Your Account / Store Information

Or drop the "Your Account" block, and have:

Our Products / Our Company / New Column / Store Information


I did tried to disable the "Your Account" module, and it didn't helped... I ended up with this instead:

Our Products / Our Company / Store Information
New Column


...is is possible to achieve the new block in the same line at all?... what would I need to do?

Thank you so much for any help you could provide,

Ana
