I recently bought the game to be able to play with my brother. I installed steam on a new laptop and logged into my old account (The one I used on my PC previously). My brother than logged on his steam account on my old PC with aoe3 installed. He proceeded to create an account and got ‘‘Bad CD Key error’’.
This was bought on steam during the summer sale. Can aoe3 being already installed interfere with the new account? We tried simply uninstalling and reinstalling libraries on steam. Also we uninstalled from control panel and reinstalled on steam platform. Still same error. This is frustrating as it is a legit copy. I can clearly see 2 different CD keys, one for each account.
Thank you for your support!
