I am also still having this issue of missing packages error. Since 03 Dec 2022, when I started the update to 1.29.30.0 it is still existent. I had not performed any hardware install or reinstall of the Sim ahead of that incident. The workaround of deleting a package doesn’t work for me, because after the re-download of that deleted folder I am always having a CTD after appr. 1 - 2 mins. Currently I am not able to run the Sim at all. Possibly woth to mention that I had not downloaded the A310 and the DC-3, yet.
