I don't know why its happening..., i have encountred this for the first time in 1.7 but it manages to fix itself, but this time it wont come back, so can i just download a pirated SP 1.9, they already got their money anyway, good thing i kept a backup so im good
@Zoomzoom999 I think he means he couldn't re-download or something.
Like, being erased from Steam/google/apple account or the like.
@TheMachinist yeah he is, pirating is not gonna get you banned (jim's case is different), it just gonna lower your reputation
why not redownload the official game and use the data from your backups to restore your aircraft, mods, subassemblies, etc?
