cheers Dave, I had a backup of the pref file,
the problem is I can load and close many songs and they appear in the recent menu all the time logic is open but as soon as I quit then reopen logic they are gone.
That will empty your list of recent projects, so that's not surprising it's empty. Try to open a project, close it, open another one, close it, etc.. for a few project, and they should appear in the list.
