sticky header: color cannot be adjusted & demo importer does not work

Hi guys,

I have 2 Problems with Restaurant WP theme.

1. I cannot install demo at theme options. The percentage goes directly up from 0 to 99 and nothing more happens.

2. I cannot change the header color from transparant to any color. I did it like in the manual but nothing works.

Pls explain any way to get successfull in this 2 problems.

Thanks in advance.
