Update: Problem solved! The problem was that I chose the wrong issuer (with the same CIV code though )

Hi,

I have bought a paper Interrail pass (Global Pass) and I am trying to connect it to my Interrail account.. But my Pass cover number is not accepted. The reason I want to connect is because I want to make reservations for the train from Lyon to Barcelona. Is there any way around this? 

Thanks in advance!
