I have played a game already with Man United and I got through registration for champions league fine, but just started again with Napoli and the game is asking me to resgiter for the next stage of the euro cup (for the first time in this save, just after transfer window). Anyway, I get the email and try to respond but it wont work. When I click on the respond button it takes me straight to the squad selection page. The area for team registration is greyed out, and I can move past this until a team is registered.
(On this squad seletion page up in the top right, you have another little menu that has shirt numbers, and registration, this registration part is what I mean when I say it's greyed out)
I only just started so it's not so bad, just I feel like I've spend 5-6 hours scouting players and staff, setting tactics and finally getting a few wins unlike Man U where I got sacked
