waypoints vanishing from the CDU route

Hi Gents,

I would like to know if this happens to you too :

I prepar my flightplan using imported routes from Vroute.

I add the departure runway, arrival runway, SID and STAR, erase the DISCOs and then push EXEC.

I can check in the legs pages that all the waypoints are present and valid.

At the end of the preflight all datas are present in the legs page.

But when airborne, all the waypoints are erased, only remains the arrival runway and the computed TOD...

I tried to uninstall and reinstall the complete PM suite but the problem remains the same...

Any idea please ?

Thank you very much in advance.
