Well, I decided I should update my sins today, but much to my horror I found I have to download impulse in order to do so.

So I downloaded it, spent 15mins trying to register and when it finally worked it would not let me update until I had registered the game as well.

The popup message directed me to the registration page and asked for my serial number, email and game.

So I type them in, only to be confronted with an error; 'Product registration failed: the email address or serial number you entered is invalid. Check to make sure that you have entered the correct information.'

Ok, so maybe the '0' in the key is actually an 'O'. I retype the number. 'The serial number you have entered is not recognised by impulse. Only serial numbers provided by stardock will be accepted.'

I double check the email address that was automatically entered for me, I double check the game which was also automatically entered for me and I retype the key twice just to be sure, but it will not allow me to register.

It won't even tell me who to email for support.
