Thanks for your help, but that's not really my problem. let me make a little summary of what i do when i want to import the flightplan:
1) i create the flightplan using Vroute (freeware)
2) i use a tool which has been delivered togeather with the concorde add-on i have, which makes the fsx flightplans into the format needed for the CIVA INS. (with the concorde this works and i can load the flightplans in the INS)
3) I select my flightplan on the ADEU unit and click the import button on it, and then the green light glows. but nothing else happens! so what do i need to do that the flightplan get's imported? (i know that it isn't imported because i look at the waypoints section on the INS)

where is my/the programms mistaked?
