Yeah, I was. I got it working now though. :)
For those facing problems, my experience was that the base game worked fine in the app, but downloading the dlcs in the app made it freak out. Downloading them through the website and then installing them in the base game's file worked, but then even the base game wouldn't run. So I uninstalled it, then reinstalled (still in the app), checked all the files were where they needed to be, and lo and behold, it works. Yay \0v0/
