Hello thereI bought the 737NG about a year ago and still have the install files for version 1.2 (I backed them up to a CD). The Windows 2000 installation that FS9 was installed on became corrupted and, having finally repaired the machine after 10 months installing Windows XP Pro, I need to reinstall FS9 and my other add-ons, including the 737NG.As far as I can gather, I can install FS9, then install 737NG v1.2, and then install SU1.3 over the top of it, giving me an up to date installation of the NG.Is this correct? I recall that there was some issue around on-line product activation with one of my add-ons at one point. Is there anything that I need to be aware of?Thanks very much for any assistance that you can give me.Julian
