hello I'm going for advice .. when logging into the game (this is a demo) so this will pop up username and password confirmed

I think that is normal message.
If you have a S1/2/3 license then it would have unlocked the game and the message would be "Welcome to S3!"
But with demo there is nothing to unlock so it only tells you that your password was correct. (in case you want to use it later on for unlock)

A lot of people have been confused by this message. It had to be set to this due to a small bug. Although it's factually true, your user name and password are confirmed - that is a good thing.

I've now fixed that so it now shows a more welcoming message, as in older versions, if you use test patch A7.
