Demo import problem, No css

Hi,

I just bought your theme Uncode, but I think there might a slight problem with it.

As you can see, I think there is some CSS missing o (buttons, colors etc.)
Is there any chance a CSS file might have slipped away when I bought your theme ?

FYI: I have entirely followed your tutorial and reinstalled the theme on my WordPress multiple times, too.

Thank you for your time.
