FINALLY Got it working.
I managed recovering projects without crashing and without faders going down at startup;
1 . Open an old project with Xtouch+Extender phisically off or phisically disconnected.
2 . In Midi Remote Manager IN THE LOWER ZONE (in floatibg windows doesn’t works) delet the third Ghost Midi Remote instance.
3 . Rename and Save project (just in case).
4 . Turn On and/or reconnect the Control Surface and open the recently saved project.
NOTE: in some cases I had to delete the TWO Ghost Midi Remote Instances. Then when reopen with the controls surtface connected I needed to add a new surface (like i had to do always, before 14.0.40). And after that, If if close and reopen C14 finally remembers the Script and its working everything propertly.
