Hi There -Like many other fellow simmers, I purchased the first release (v2.00.0030) as soon as it was released and like many of you I too experienced difficulties and was not able to get the simulation going. I waited until earlier this evening and downloaded the newer version (see subject please). I used the (ADD/REMOVE) feature of windows to remove the first version. Once I felt sure it was completely removed, I then proceeded to unzip the newer version, so far so good.I then clicked open the file PMDG747_400_FSX.exe and it started to do its magic to then have it all stop with the following message, and I quote..."FSX Version 10.0.61355.0 (SP1 at least) required. You only have FSX Version 10.0.60905.0 installed. Please install FSX SP1 or later to use this product" end of quote.I must confess I'm having difficulty understanding what that message means. I consider myself average at best when it concerns computers and computer related terminology, so please excuse me for that. Still, I'm hoping someone can perhaps explain to me in plain english what this means and what I need to do to get the queen going and me along with it.Thank you in advance for your kind help, Jaime

Exactly what it says.Michael J.
