I recently bought CKII on Steam while it was 75% off. However, I have been experiencing fatal runtime errors with the game and I cannot post in Tech Support without using my CD key. Where things get dicey is that I only have CD keys for a select few DLC's on my steam account and do not have the CD key for the actual original game, even though I spent $40 for the entire collection. Steam hasn't gotten back to me for my requests. Is there anything Paradox Interactive can do to help me, or am I just screwed out of $40?
