It might catch itself but if it's still stuck then downloading the chain snapshot (1337-snapshot10082017.zip at the time of this post) from https://github.com/xenonflux/1337/releases and replace your files with it (you don't have to replace the conf if you have working custom one) would be way faster. If you have the room on your harddrive(s) then keeping a copy of those files gives you your own fallback option btw., especially useful for coins without such good support as 1337 gets from devs and community.
