I'm not the same player/person you asked the question to but I've also received the same problem.
The error message I receive is the following "There was an error communicating the Football Ultimate Tram servers. Please try again"
I then try again and I receive the same error message each time I try, thus making the "Please try again" sentence very unnecessary.
EA should fix this immediately as it's ridiculous considering the "82+ Player Pick" is repeatable infinitely for a finite amount of time therefore I should be able to submit as many as I like.
I'd like to know when this will stop considering I've it's been happening for roughly 6 hours now.
I'd also like to know whether this error will occur again in the future? If so, how can I avoid it, I need to know statistics; doing "too many within a short period of time" isn't a good enough answer.
Thanks.
