i had everything working for fs9 then i went and set up fsx and now i keep geting the registration form again now fs9 don't even work i would like to use rc4 for both. what am i doing wrong, thanks

you have to install 4.3 for both flight simulators. two seperate directories.the 4.3 install gives you the optino to do fs9 and fsxso you might need to uninstall rc, and then reinstall with the fs9 and fsx optionjd
