Peoblem with Facebook-awd plugin Smthemes Theme - Garage

Hello guyz.
i have some weird problem.
i just started using today wordpress, and i got a problem.
when i try to activate the Facebook-awd plugin seperatly it works.
<a href="http://wordpress.org/extend/plugins/facebook-awd/">http://wordpress.org/extend/plugins/facebook-awd/</a>
when i activate any of Smthemes they work great also!
<a href="http://smthemes.com/">http://smthemes.com/</a>

but i cant run them together! if i activate one of them while the other is already activated my site is just not working, i got like a blank white page!

1)i tried everything, change themes, it happened only with Smthemes.
2)i tried all their themes, and they all built very similar so i think thats the reason why all of them wont work togheter with the plugin.
3)i tried other facebook plugins with those themes and everything workked perfect.

i red that it could be that these 2 mods are conflicating. because the theme has also facebook widgets built in.
if it is important i use the "Garage" theme.

i need help, thanks alot!!
Mark.
