Retro discount?

HI,I purchased the MD-11 for fs9 when it was first released (great plane, by the way!) never thinking I would be upgrading my computer to run FSX...Unfortunately,I have recently had to buy a new computer because my old one, suffice to say, "is no more". My question, of course: Is there a "retroactive" discount available for me if I now purchase (only two months later) the FSX version...since my new computer can handle the system demands of FSX.Thanks,Bob
