City Navigator Europe NT 2020.10

I think .msi installer is irrilevant, I never used it, just copy the .gmap folded in right path.

I've notice that the entire folder C:\ProgramData\GARMIN\Maps\City Navigator Europe NT 2020.10.gmap\Product1\CNEuroNT_2020_10 is missing
Looking into Logs files some HASH Errors are repaorted and downloads stop.
I guess this is the problem
What I don't understand is how the Maps could have worked yesterday. Maybe I had hallucinations
