I've downloaded FG 2.10 and downloaded the A330 fro the omegahangar. Then installed it by these steps:
- unzipped master.tgz downloaded
- putted the folder automatically named "fg-airbus-a332-airbus-a330-200-main" on my desktop
- opened fg 2.10
- went to "Others" section
- clicked on "Install Add On Data" and selected "fg-airbus-a332-airbus-a330-200-main" folder
Then a window said me that the file was correctly installed in the Aircraft folder. I started the simulation but the aircraft cockpit was someway "invisible". The whole aircraft is "invisible"! How can I do??? Please I really want that awesome plane!
