In 2014 I bought Victoria II and in 2015 its 'A House Divided' expansion using a site called "Gamesrocket". I can't add the license keys to my Steam account, so I'm guessing they're either expired or just can't be added to Steam. Now I want to add the 'Heart of Iron' expansion to it, and start with a clean install.
I've reached out to Gamesrocket to renew my download links (I messed with the files for modding before I learned how to do proper modding). The first one didn't work but I'm still in contact with them about it.
Now I'd like to know:
- will it give issues when trying to add a Steam-bought game expansion ('Heart of Iron') on top of my non-Steam bought versions (the base game and 'A House Divided' expansion)?
- Or should I just buy all three from Steam again as mixing those would cause strange errors?
