Can´t even download it... looks like the file is way too big for mega.
It only allows to download like 2.7 GB and then it throws an error mesage.
You've probably figured it out if this is the case, but have you hit your daily limit for mega? It's 5gb total day. If that's the case, just wait until tomorrow and you should be good.
Bad news... its tomorrow and same thing happened, and i have not downloaded anything else with mega so it should be ok but sh*t happens :(
