When I check for updates through the program, I get a response that all files are up to date. I've gotten this response for several years with no apparent updates. My Live Sky menu does not offer the menu option to "Update Comet/'Asteroid/Satellite" files. I have Starry Night Pro Plus 6, version 6.3.9. I notice when I go to your website that there is an update available labled "6.3.3 to 6.4.3". Is this an appropriate update for version 6.3.9.
