Recently, there have been some problems with the pack and the launcher that have prevented some players from installing the Galaxy-Craft Modpack. Most often, this is the problem stated in the title, but it can get stuck on other steps too.
I'm currently testing on a fix for this, and should have it out some time today or tomorrow. I apologize to anyone who this has affected, but hopefully we will all be able to play together on the server soon.
