In fact, I can't do anything with Music Creator, I can't even open a Demo.  I'm reinstalling because I lost my hard-drive and have had to re-install everything on a new SS drive.  I'm using Windows 10 - but it all worked before the nasty accident.  Can anyone help please?  Thanks John

MASTER.INSTS are contained within the program and I'd think it means there's been an error or the complete program hasn't installed successfully. Could be to uninstall and remove all traces, then reinstall the software may work.
