thanks for the responses.
I am stuck in the twilight zone.
I have just tried creating an account but apparently I have one???
So I tried to recover the password (which I haven't created) but no email is sent to the email address, which is strange because I got emails when I purchased the game.
So I can't create an account and I can't get emails from the account which apparently already exists. No emails in junk folder either.
I am very annoyed and will probably just ask for a refund when all I want to do is play what looks to be an excellent game. Dreadnaughts on the other hand installed no probs??
