The winter schedule for trains was just released - and I am trying to book a seat on Dec 18 from Frankfurt to Paris. When I select the time/fare I want, I am prompted to complete all the info, including my payment info. Everything seems to be fine - and then I get a message saying the train is sold out....even though the seats were just released a few minutes ago! I've tried using Bahn site - and get the sold out message. Then I tried Captain Train site and all is fine up to entering payment info - and then I get an error message. Does anyone know why it's impossible to buy a ticket? I've tried other time departures and get the same messages (sold out or error). Help?
