That kind of thing is an OS problem, rather than a Logic one - everybody that's used a computer has probably had that at some time or another; even though you know the file isn't being currently used, the OS seems to think it is - usually re-booting solves it - occasionally, the worst scenario happens and you might just have to delete it because its gonna be less time consuming to rebuild it.
In the case of preference files, Logic does its best to rebuild them when you start it up again, of course you may have to reset particular preferences, but its not that much of a tragedy, really.

I made it. I trashed the preferences file and rebuilt it in Logic. Now it's visible and I could backed it up.
