What is the meaning of the prohibition sign on the left side of the file name in mediabay?
Hi and welcome to the forum,
This has been discussed many times here in the forum.
Make sure, your have a valid license for the given library.
Try to set the MediaBay’s factory settings by deleting the MediaBay component preferences folder:
%appData% \Steinberg\Steinberg MediaBay Server
That the license is missing for the content. See @Martin.Jirsak’s post for the solution
