I recently upgraded to a new computer with windows 7 and I am experiencing a problem when trying to use carriers I used in XP.  Loaded everything in and they show in the add-on scenery area, aircradft show up on the carrier, taxi into position, activate the cat, throttle up and hit the brake to launch the cat, and instantly the program exits and I'm back to t he desktop.  ?????????????  I've set the program to run as admin with XP SP3 compatability, but still the same outcome.???????  Any help would be appreciated.   Jim
