Hi

I downloaded a skin, from http://www.deviantart.com/deviation/32823793/
It works great and I love it, but I have one small problem

this is how mine looks like:



The problem I have is, why do i get that little empty white box, why isn't it the same colour as the rest?

Compare mine to the:  http://www.deviantart.com/deviation/32823793/

You should see the difference, I know its only a box but its really annoying

Can anyone help me?

Thanks
