So who owns the VC plugin?
VC-64 was a Cakewalk reskin of Kjaerhus Audio's Golden Audio Channel (
http://www.kvraudio.com/product/golden_audio_channel_gac_1_by_kjaerhus_audio). That company, which was either a one-man shop or very very small, went out of business years ago, leaving behind an angry throng of users who could no longer activate any plugin they bought directly from Kjaerhus with its challenge-response scheme.
I don't know if Cakewalk has the ability to contact the company's founder and secure any additional rights for VC-64, but honestly, there are much better plugs out there these days.
