If you purchased it from the FM online store, or perhaps if you just registered it with FM, they should be able to provide you with the download link. I have done this with v.11 and 12 for various clients.
Also, I have the upgrade CD for FMAdv v.10, but I don't know if that will help you. You're welcome to swing by and borrow it if you like. Send a pm to firstname.lastname@example.org
