I updated my 747 to the universal update ..no problems...then I had a problem with my computer.I thought it was because of the update....long story short I deleted the update and the original 747...now when I try to reinstall the original 747 it tells me "its an earlier version" and it wont let me re-install! I've try'd everything I know including trying to erase all through re-edit...but it still tells me theres a later version ...Please if anyone can help. I sure dont want to format if I don't have to :( I know I messed it up it's not PMDG's fault!!
