So, I picked up EU3 from the GameStop app back in 2013 or so, but never got around to registering the keys, as I didn't need tech support for the game at the time. However, it seems that this is now biting me in the butt, as I now need support since the game crashes when trying to load a map, even the tutorial ones. I purchased the Chronicle edition, but entering my key isn't accepted as a valid one. As the Gamestop App shows the different pieces of the game, I attempted to register each of them separately, but to no avail. What recourse is there for this?
