Have a read of the main VeriFLY thread in this forum, mainly the last few pages, and you will see you're not alone here. You did the Salesforce route, and you only get one shot at it, whereas VeriFLY once you have a green tick you're ok and you can keep trying until you get the green tick. Best to use the PNR / booking reference route, rather than selecting the flights, due to teh connection. OLCI may open up to you later today, it may be you are actually OK, but the Salesforce route doesn't work so well if you have a connecting flight.
Almost certainly Bremen will say "sort this out at check-in", since this flight will be under airrport control.
