Sounds preposterous that 'too many accounts' is a thing in a game that literally used to allow unlimited accounts be created It’s never been shared with anyone but myself, but it’s true I had a lot of accountsĬan’t you delete old accounts? I don’t have any of them in my memory anyway What do you mean it was shared in the past Sadly in these cases there is nothing we can do I’m very sorry Yes it seems the key is in use this may be cause it was shared in the past, there are lots of old warcraft III accounts associated to it. I contacted technical support, and I am utterly disgusted by the way this was handled, effectively telling me that this is an issue that is not caused by myself, but an issue that they cannot fix and one that means that I need to re-purchase the game.

I created a new account (through warcraft 3) and proceeded to log in - only to get this error saying that my key is already in use.

After 15+ years of having not touched War3 ROC/TFT I decided to find my cd-keys from my old account (which I did by contacting support) and then installing the clients.
