Family tree software

[Computer]

I have downloaded software called "ancestry Family tree" You can DL it at http://aft.ancestry.com/?rc=locale%7E&us=0 My question is how do you get the chart to display siblings. I know you can can change the chart between siblings. for example. The only chart i can display are direct ancestors ie. parents grandparents ..
there are no sibling or cousins or aunts on anything other that parent or the person selected. If I select my uncle it wont show My mom, or other uncle or any of my cousins just His parents and their parents. etc. Is there a way to show the entire tree so it will show all my siblings parents cousins aunts and uncles and not just my direct ancestors??

thanks for the help.
