Error message when Game is starting (translate from German):
Error with User permissions
Reason are your account settings that prevent you from access to certain game features. please check your accout settings on xbox.com to get further information.
If I check my settings I do not get any further information and have no clou what his might be. Please be more specific with such an error message. I was able to play the beta without any issues, did you may screw up my account after shutdown of he beta?
I had the same problem and also checked all privacy settings at https://account.xbox.com, changed a few there and saved. Did you also run the benchmark test? I can’t say exactly which of those two helped. Furthermore I did get a few confirmation e-mails about apps that got connected to my account. I would recommend to check if you have received these too.
Tried the same and are able to say that it is definitely the privacy setting. I doubt it is the setting who is able to view your profile. This need to be confirmed, because I changed a couple of settings back and force.
