FMGS server B49.0 error help needed

Hello guys,

I am facing a problem with the latest "B49.0" release. After i finished the setup i started the pd v3.4 and load a flight.
Then i started the "StarterENGRUN" in server pc and also in client pc's. Everything loads properly but after a minute
on server pc on fmgs module i start to get on screen many messages telling this " Invalid file name - %s." and everything has disconected.
Any ideas?
My setup is: one pc runing p3d fmgs server and ecam plus fbw and overhead. two clients pc's running rest of sofware.
Many thanks in advance.
I am attaching two pictures.
