Can't make ANSI sprockets

Hi all,
This is my situation:
I'm using Solid Edge ST6 with Engineering reference and Machinery Library and Standard Parts Admin and I need to make ANSI sprockets. The thing is these sprockets are the only thing I can't make. I tried reinstalling everything and I didn't work.
I REALLY need to make this sprockets. Any ideas?

UPDATE: I can edit ANSI sprockets assemblies made on other computers
