It seems that a file which is essential for the projects wasn't found. The problem is probably that the Music Pack you've imported wasn't imported correctly. When you import a Music Pack, a dialog appears showing a progress bar which indicated the import progress. While this dialog is open, you cannot interact with the main window - when you click on it, you'll hear the "bell" sound. So I guess that the progress bar dialog was hidden behind some other windows while you've imported the Music Pack. Then you did terminate the Music Pack Creator, which left the half-imported Music Pack Project in an undefined state. So in conclusion I suggest you to delete the corrupted Music Pack Project and to re-import the Music Pack. If the window freezes, minimize other windows to look whether the progress bar dialog is behind them. At least wait for some time. Then post your logs again.
