Try clicking save, instead of run on the download, if downloading mirrors. if downloading from torrent I have know idea what the problem could be cause I use the mirrors.. any ways.. that should stop the redownloading after every crash.. unless its your pc crashing on you and not just the game, if that's the case download it, restart your pc, so your pc saves it.. then try and play.. but I still don't understand why you are crashing... unless you barely have pc requirements to play.. (if so turn everything down in the in game settings..)
try this if it doesnt help let me know ill look into it deeper for you..
PS. server is not down im currently playing
