Hi, I have been enjoying MSFS 2020 with absolutely no issues. Today I downloaded Update III (GB) but when it got to 174/175 file downloads; (about 22.38GB out of 22.45GB) it reset then commenced to install all the 83GB of base files which were already installed. I have a very slow download connection and 80GB would take about 23hrs so I aborted this. Please note I installed the original via 10 Premium Deluxe disks which I had purchased in Dec 2020. I followed the Microsoft help which said to attempt a repair but this had no effect. Then a Reset & again no effect. I reluctantly uninstalled the whole system then reinstalled all 10 disks but the problem now is it will not accept the license code since it has already been redeemed. This is confirmed on my Microsoft account. I have tried to ‘talk’ to a disembodied help assistant but this is as useful as an ashtray on a motorbike. I would appreciate any help. Thank you
