SpeedRunners: FortKnight's Fast Faction

Pretty self explanitory. I bought the add-on, worked for one day, then says it's installed but it doesn't work and tells me to buy it again. What's with that?

lol

i love this game but people are turning away from it because of reviews

dlc is broken. says i own it in store but will not load in game

Don't trust those other reviews, this pack works.
