I mistakingly used my GalCiv3 Humble Store key on a different Steam account on my computer. Since I don't think that can be fixed, I'm trying to salgave the situation by playing from my account through Steam's Family Share, but I get the following error message when launching the game:
"The following DLC folders are in a state of partial install:
DLC1_MapPack
DLC5_Buildser's Kit
Please exit Steam completely and check task manager to make certain that it's not running, then start it up again and validate your files. If the problem persists, please see our troubleshooting guide or file a ticket for assistance:

I followed all the troubleshooting steps on the first link up to and including "The Purge". It didn't fix the issue, so I submitted a ticket as instructed. Their answer was just to post here. So... help?
