I wonder if you could be so kind to have a look of  my site
www.turismosostenibile-idee.com
can you undestand what is wrong on my arras theme 1.5.0.1 download fromhttp://wordpress.org/extend/themes/arras
as it doesnt show slideshow and all the other items thumnails, ecc. - look like a plain page  
To make more clear what I mean is that i suppose I should have a page like:
http://www.arrastheme.com/forums/   click on preview
is this correct or I have to make some setting or add plug in or??? Please be so kind to try to explain to me.

my wp : WordPress version: 3.0.4     You have the latest stable version of WordPress.
Your table prefix is not wp_.
and the given theme was Twenty ten - i did change from wp page : theme-install theme
Any tutorial step by step to make it from the beginning and learn how to use it?
in my language(italian) i do not find anything.
What do you suggest me? Is first time I try to change a Theme and make a web site, so please explain to me as easy as possible.
thanks in advance for yr support.
thanks a lot
