Thank You for your reply.. I may have solved the problem...instead of using the download link from FSPilot (where I bought the program), I went to the FSDream website and downloaded the installer from there. After reading about other issues on the forum, I figured I had nothing to lose so I installed GSX Level 2 from there. The program installed, I went to a flight that I had on the ground, asked for boarding and, everything showed up, the vans, buses, crew, passengers, etc. I haven't gone back to the program today, but hopefully it is fixed. If not, then I will try the FSX.CFG solution that was recommended above. Thanks again for your help.
