You can still download your products and keys at
www.cakewalk.com/My-Account/Products. Obviously you need an Account and have to log in. I still have my old Cakewalk Mp3 Encoder Download listed. But I didn't do a reinstall since the shut-down, I don't know if activation works? However, if you've bought the encoder through your account, it should be listed. Or maybe, you renewed your Account meanwhile or cakewalk changed something back then in acient times? BTW - CbB is free and great and has an onboard mp3 encoder
Cheers :)
Edit: I just realized, the Link above doesn't work. Funny thing is, when I go through the menu at the cakewalk page (Support - My - Account - My products) I have access to my Product List. Don't know . . .
