I've suddenly started to get the error parsing, even though it was working a minute ago. It seems to suddenly dislike my dropbox URL, see the console output below:
org.spoutcraft.launcher.exceptions.RestfulAPIException: Invalid download url for this pack: https://dl.dropbox.com/s/redacted/redacted.zip?token_hash=AAEYdpBmDqe7--syC03hR-AMQsydUqmbSf1exUdobRSjnQ&dl=1

I tried changing the dropbox url to a new one, but the problem remained.
