FS-Cast B17 install problems

I bought the CD version of SkyUnlimited Productions FS-Cast B17G. I ran the install executable, but I can't get the aircraft to show up in the sim. It looks like the installer put things in a folder called Microsoft Simulator X/Sim Objects in the main FSX directory. Shouldn't everything be located in the main Sim Objects folder and do I need to move things to their proper locations to get things to work? And what folders do the accompanying effects files go into? Help!
