I am logged in as i should be but i cannot access any server and the marketplace is greyed out. I have tried logging off then back on again but it makes no difference. In the Data menu everything is on. I even made sure my xbox networking is all good. Any ideas?

Got it sorted. I read to do the following. Type in Windows search Xbox Console Companion, Log out of Xbox Console Companion then log back in again and hit Lets Go. Restart MFS and your good to go. It worked for me.
