It is not working as expected

Hi, I just bought the "Coming Soon" and facing the following problems:

1. The YouTube video does not playing
2. The login fields are disabled
3. My message from the home page displayed with Italic font
4. I expected my message to be justified in the center of the screen and not to the top
5. The background is not black as the intention was
6. The Login page has the fields in English and the button in Dutch

Hi , thanks for your answer.
An addition problem is the fact that the pages are not appear in a different page therefore the links on the left side are not working

Hi, I found a bug in "Contact Us" tab.
The "Phone" check box disables the "Your email" field instead of the "Phone Number" field and vice versa!

You can login now, thanks.
Please do not forget the rest bullet points that still open:

Home tab

My message from the home page displayed with Italic font

Front end

I expected every page being justified in the center of the screen also vertically and not to the top (now I have top margin)

"Contact Us" tab

The "Phone" check box idisables the "Your email" field instead of the "Phone Number" field and vice versa!
The button "Send Us" does not do anything when it is pressed!

I assume that when you are done you will let me know what the problems were and what you did to solve them!
