Downloader issues (wrong hash)

Hi GGG,

first of all - thank you for the recent expansion & great league! Amazing job, having a blast.
Only the frequent crashes are little bit annoying, I've decided to reinstall the game, hoping it would help, but I'm not able to download it.
I keep getting an error message mentioning wrong hash of random files (I tried to download it 4x times, took couple of hours, I made sure I do not download anything else, but no help).
So it seems the downloader is not perfect.. please consider looking at it and try to make it more safe - "bad-connection/interrupts-proof".

Is there a torrent available for the latest release? Now I'm trying to reinstall it via Steam, fingers crossed, but I don't like using Steam..

Thank you,
Kind Regards,
Karel
