Logo position Minimable responsive theme Help

Hello,

I have installed Minimable Responsive WordPress Theme
I have a problem with change logo position. Now is on the left side but i really need it in centre.
Unfortunately, the current solution is in my case completely symmetrical.
I serch solution in 3 files with styles, but I move all containers.
Of course, if it make things easier paste a piece of code, but which one?

Thanks in advance for your help.
