Purchase and loading

I start the sim, in windows 10, I am then prompted to update, after 3 hours the first block are downloaded, fs-base-0.161.fspackage.1 thru4 etc all the way down to fs-base-0.1.94.fspatch…when decompression reaches fs-base-0.161.fspackage.004 it stops working, so I try again and again and still the same, then I see the work round to delete none working folder and then the same issue with package 6 and on and on and on. I am now at the 49 hour point and am really not happy at all with the entire situation
