How to change the page orientation in Acrobat Pro X

Hey guys,

I just created a PDF with Acrobat from a HTML file, it did it but the pages are set as landscape, I want to have them as Portait, I tried printing it as PDF in portrait orientation, but it only put what's on one landscape page  in in one portait page without moving the text from one page to the one before to fill out the empty space.

So, how can I do this:

Change the page orientation fixing the content at the same time.

Here is a picture of what I DON'T want.

I want the content to fill up the whole page.

Thanks.
