Microsoft Flight Simulator downloading problems.

Hello, I've bought Microsoft Flight Simulator Deluxe Edition this summer, I've tried then to install it, but I had the same problem, when i'm installing it, it get's to like 20-30%, it stops downloading, I have to re-enter the game in order to start the install again, but this time after 8-10%, the download stop, and the download speed goes to 0.00, and it reverts back to 4-5%, like a loop, i've even tried reinstalling windows, drivers, but I gave up, now I've tried again, it's still the same, any idea why? any help would be very much appreciated.

:)
