Okay so I tried that, still no luck.
I tried to fly the F-16C, and got a slightly different error:
same... same...
The error message shows some mat files / msh files are missing.
But they are composed in the archive.
Only failed to extract them from the archive.
Your downloading was corrupted and the archive file was broken, or your extracting tool cannot treat the archive right.
The folder "!_F16A&C" has 961 files in 33 folders.
Does your downloaded archive has those numbers of files?
