Guild Wars 2

This isn’t the first time something like this has happened, every patch I do crashes then I restart it and repeat this until it finishes, but my main problem, is I had to redownload gw2 because of windows 10 upgrade for some reason, and my download is really slow, ive been downloading for 3 hours and it is only at 4 percent, anyone know what is going on?
