Hi,I downloaded and installed SP1c on both variants on NGX, but did not have enough time to install my liveries before running to the (RL) airport...do I need to redownload the mcphat installers again? I remember someone saying they change the key everyday or so...

no, just run again the installer you already got with the normal serial and there you go!

I've simply copied the [fltsim.X] data from the aircraft.cfg from before the SP. Works perfectly.
