In order to run the Dreamscope musicdisk, you have to start it from the
AmigaDOS (with NO Workbench active).
To do this, reset your computer (or run the LOADER program from the workbench)
and press down the left and right mouse button simultaniously. You will start
the Early Startup Control program that way. Here you can press BOOT WITH NO
STARTUP-SEQUENCE to get into the AmigaDOS. Go to the directory you installed
Dreamscope to and launch it by typing Loader.
