Stuck In View-Only Mode
what has happened is, the "real" Dinradio.m1 libraryfile was not re-writted back to the network drive.
if you look closely when you first start Music 1, at the opening window just before you open the databse, the extension is : .ml instead of .m1 that is the read-only copy of the database.
when you start Music 1 in multi-user, it makes that read-only file and brings a 'clone' onto the c drive and into the Music 1 folder there. this worker is named: ReadOnlyTemp.m1 when you finish work and quit Music 1, it moves the ReadOnlyTemp.m1 back to the network drive and over-writes the file .ml file, replacing it with the updated DINradio.m1
first, look into the c:\music 1 folder and see if you find a ReadOnlyTemp.m1
if you do, CUT it, then PASTE it into the folder on your network drive where your Music 1 library/database file is kept. In that folder, you will also find the DINradio.ml file. Delete the .ml file, then rename the ReadOnlyTemp.m1 file to: DINRadio.m1
