There was a message in the B77 forum saying:
"Captains,
It appears that some of you are not aware of ACE existance and/or purpose.

The ACE (stands for Aircraft Configuration Editor) is a free utility that helps you with CS products."

I am well aware of ACE and used it for my liveries for instance.
BUT today I needed it to configure a flight, wanted to change lbs to kg, add passengers and cargo and SAVE it.
Unfortunately there was no button to be found anywhere to SAVE my changes   

Please help me to find a way to save those settings and use them for the next flight.

THANK YOU!
