distribution builder engine file

[John Tenny]

I'm actually getting my first stack to work (thanks, sims) and wanted 
to try the distribution builder. I downloaded Richmond's Expanded 
Distribution builder and replaced the one in the Tools folder (glad to 
be able to see the buttons).

I replaced the distribution builder cause I couldn't see the buttons.

Went through the steps for OS X, selecting the stack, making it the 
main stack, no other changes. Last button resulted in.....

"Can't open engine file/Applications/Revolution 
2.0.2/Revolution.app/Contents/MacOS/Revolution"

I'm using the Studio edition on a Mac with latest X system and Rev 2.0.2
