There was a message in the B777 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!
