Report SonicStage 4.3 library issues in Software Posted May 1, 2010 · Edited May 3, 2010 by Avrin Maybe something is wrong with the SonicStage database file. The file is located in the "C:\Documents and Settings\All Users\Application Data\Sony Corporation\SonicStage\Packages" folder and is called MtData.mdb (there may be other files with similar names there, e.g. MtData1.mdb, $$MtData.mdb, etc., which are backup copies of the main database). Try moving the file away to a different location, and delete any backup copies (but don't delete the MtType.mdb file). Then start SonicStage, and it will create a new empty database. Then try importing music into this new database.
