Hi,
I have the same issue. I thought at first it must be my end, as double clicking the icon on the desktop or the entry in the start menu had no effect, it just would not run. This happened just after I updated the A300 V2 to 2.01 - I guess it must have updated the inibuilds manager at the same time? I updated the aircraft, closed the manager, loaded up XP to find that I needed the serial key to activate the aircraft again, but found I could not get back in to the manager.
Thanks for the tip on going into the folder and launching 1.0.3, I would never have thought of that. Finally got my key to re-activate the aircraft again!
