Hi Bordo14,
Thanks for your post and apologies to hear you're having an issue logging in to TV Go.
As the error is showing the username or password as incorrect, can you please try resetting your password via My VM please?
To do this sign in to My VM and go to My Profile. In here you can update the password. Once you have done this, please open TV Go either in a browser or the app and try logging in using the new details.
As a side note, make sure you are typing the details in and not relying on auto fill details as these can sometimes add a space which makes the information incorrect.
Pop back and let us know how you get on.
Thanks,
