Blue screen while downloading = client redownload.

Similar thing just happened to me:
My game randomly crashed and gave me an unclickable (lagged) error window. I then ended GW2 process, ran launcher. Two windows opened – the launcher and some random file rapairing window with some load progress bar. That new window loaded up to like 10% and the main launcher window started downloading 200.000+ files, the whole game.
So I just decided to cancel the “fixing” and redownload/reinstall the game to a new location with a new downloader, maybe it will reduce the bugs I brought from the betas
