CDU pages not updating

[sameermankame8960 1]

Hi there. Just did a short flight from VOBG to VABB. Everything is fine, but i was not able to update the FORCAST page with the winds and RTE and LEGS pages with the new waypoints after starting the descent. In the FORCAST page i am able to type it into the scratch pad but cannot enter it in LSK corresponding to winds information spaces. It also says invalid. About the RTE and LEGS page, I am not able to any way point after executing the flight plan. Though typing it into the scratch pad it just stays there. Can somebody tell me what is wrongThanking YouSameer Mankame

The flight director thing is correct. As for the cdu update, I can't help you as it's never happened to me. Do you have sp1 installed?
