I've also had this issue today. This is the first time I have loaded the A340-600 with the current nav database. The navdata had apparently updated to the latest AIRAC as expected, but the only way I can get the flight plan to upload is if I select "IGNORE AIRAC/AC TYPE MISMATCH".
Looking more closely at the MCDU I noticed the end date for the AIRAC was incorrect. It shows 16MAY-13MAY, not 16MAY-13JUN, and the database number is one cycle out too (2604 not 2605). See screenshot. Could this be why the flightplan is not accepted?
Edit: l now realise the reason, the EFB never asked for my Navigraph login and as I don't have the charts service I forgot that would be needed. I was thrown off the track by the nonsensical cycle number the system created.
Problem solved and lesson learned.
