CDU PLN STEP and ABM not working

I'm trying Magenta software on my system to be expert in a bit, but I have a problem on the CDU about STEP command and ABM.
The software versions I have are 406 for CDU and 438 for MCP .
When I run on MCP setting PLN command it normally appears on the CDU LEGS the CTR word written on the first line, but after I'm unable to move it down to the other Waypont legs because on 6 right key I have RTE and not STEP command.
Finally, when active FIX page I get all the data correctly on CDU and ND, I'm not able to work the ABM command nor to get any data (even in flight)
We precise that my system has WideView and FS9 on the server (which runs FS in the background) together with the CDU and MCP CPFlight, while PFC and ND are on a client.
The system NetDir and everything other commands work perfectly except the two commands that I have reported.
I tried to reinstall CDU and MCP upagrade but no change.
Thank you for your replays
