Vista Style Builder

Hello!
Yesterday i´ve buying VSB and now, after many hours testing without a result, i think it was wrong to buy this app.
In another forum i read: with VSB it´s easy to make your own VS.
So far, so good, but how can i make it?
There´s no helpfile, there´s no tutorial for beginners.
For example: how can i change a Vista VS to a Win7 VS? (i have Win7 RC)
or: how can i make a transparent startmenu?
Have anyone a link to a tutorial?
Sorry, for my bad english.

Thanx, ablev
