Ideas
There are at least 15 threads about this error - and the "community managers" didn't respond to any of them. Except for two thredas: one that was posted in a language they didn't bother to translate and they closed it. And in another one they said, it's supposed to be an PSN-error, not EA FC-specific including a link to a troubleshooting page "How To Fix CE-108255-1 Error". But the the proposed solutions didn't work for almost any of us:

While it CAN be an PSN-system-error, it's mostly because of an corrupt EA FC database, that is broken in its core. But while many of us tried to tell them for over half a year now, nobody cares - as you can see here:
