My saved Themes don't work

Hi,

i saved a few of my themes, but when i try to load them after i've started up my computer, it won't load them. it just loads an empty screen.

also, why doesn't avedesk start when i start my windows XP?

Well i Have to say that You Should Get Vista OS X here http://patrickgs.pa.funpic.de/index.htm

it works with XP also
