It should be quite easy if you still got the installers still on your pc still when you have first bought the pmdg aircraft. if you havnt than it mite be a problem since the link mite have expired in your acount. If it has than you need to purchase the extended download service. First you need to uninstall the pmdg aircraft using the installer option or using the control panel remove/add option. Than make sure there are no left over panels etc in fsx. simobjects airplanes folder. Than it just a matter to reinstall again than install the updates. If you need to download again than you dont need to update since it comes with the latest updates.Or you can try the repair option as well in the installer as well
