Commodore Remix

Hello all,
I am trying to get Future Composer to run on my Amiga emulator (WinUAE) but I do not know how to get it to run. I tried ADF Opus to make an ADF file to put it on so I could use it as a disk image but when I try to load it in the emulator it says "The selected floppy disk image is not bootable (boot block checksum error)." Any help would be greatly appreciated.

One of my mates might know how to do that, I'll get in contact with him and see what he say's and get back to you.
