Problem with "Downloading" -

Ok, so I took a leap of faith and ordered. I started to download and realized 1.3gb in that my AV was slowing me up a bit. Not to worry, I just turned it off, restarted the download and to my agonizing surprise, it's now going all through it again? Shouldn't it resume where it left off? Is this something that may be fixed for future issues? Also, it's "patching" to where I left off. It now only shows 1.3 gb for the game. Before it showed 3.something gb. Will it just keep going when it gets to the point where it left off? Thanks!
