Took you the whole night only? Took me he whole night and am still currently downloading the next day. Its now 5:52pm and I have “3gb” left I’m trying to download. I’m having the “initializing” bar and the “0mb/s” bar and yeah, my internet is bad but the Battle Net launcher is the worst. People say just wait it out. Ok I’m waiting to download 3gb left for the passed 2 hours....

so i found a completely new fix, you can delete a file from the game and let it download once again. i think if the download is too near to the end it will just get stuck so you can actually reset it like that
