America West A-318 803 by Francisco Escudero fails to load.

I have just downloaded Americal West A-318 803 by Francisco Escudero. When I choose it from the Aircraft menu when the program is running, I get an error message that says it is unable to load for a number of reasons. I have installed the 9.1 patch from Microsoft and still it fails to load. I have this aircraft running just fine on another system...XP...this one is Vista.
Suggestions?
