Tried that but without success.
I did a search on my pc to see where the 2109001.rom file was being saved. The only entries i found were in C:\FSlabs\navdata and C:\FSlabs\navdata\navdata-backup.
So all my attempts to place the file in the other folders has not worked. Another interesting fact is that the two 2109001.rom files found were dated 26/08/2021 which must have been the date when I first tried to update the Airac. All my subsequent attempts have not generated a 2109001.rom file.
Does that give you any clues? It is a shame I am having this problem because I love your products as they make flightsim so realistic. At least I have the 2101 Airac cycle which is reasonably current, better than a 2018 or 2019 one.
Your FMSdatamanager seems to park the new Airac files in the right place for my PMDG, Majestic Q400, and Active Sky products. I did run a scan in the FMSdata manager but it could not find the FSlabs A320 hence why I have to manually download. Is the FMSdata manager a possible route to overcome the problem.
