When do you want to travel on the Eurostar?

There is a limited number of pass holder seats on the Eurostar and on popular departures and during high season those sell out weeks, and sometimes months in advance.

The best place to see the availability of passholder seats and make reservations on the Eurostar is 

https://www.b-europe.com/EN/Booking/Pass#TravelWish

Press "later trains" and eventually you will find the next available connection. 

If you have a mobile pass you need to generate a Pass Cover Number in order to make the reservation at b-europe. You do that here in the PCN generator:

Why is so bad ? I need help please i must Move on.

I suppose you mean a reservation? If you have a pass, then that is your ticket. Why it doesn't work is impossible to say if you don't say where/how you are trying to book and what happens when you try.

There are up to 4 direct trains per day from Budapest to Bucharest. Reservations for the night train leaving at 22:45 can be done online via tickets.oebb.at. Do NOT use "Seat reservation only” but add the Interrail/Eurail discount and then look for normal tickets. All comfort categories are still available.

Reservations for the other trains (1 day train and 2 night trains) can be booked by phone or at a ticket office. Also in Germany.

If you want advice on how to book other trains, then please specify route, date and departure time for each train.

I have the rail App and the rail Website
