It IS legal to share, I just got this permission letter from Mike:
Hey Chris,
That's so great! I knew the forum crowd could pull through for you. There's really nothing keeping you from using anybody else's copy at this point, as Cakewalk (the company) has been closed for awhile now. BandLab acquired the IP and some of the assets, but that should have no restriction on your usage.
Great to see the Cakewalk community coming together to help! If there's anything we can do in the future, just let us know and we'll be happy to assist.
Best,
Mike
So... if you have the original disk and serial number (which is NOT on the disk), and are willing to send it to me, please email me at chrismohr53@gmail.com to agree on details. Thank you! Chris Mohr
