Alceste

Good morning, I am an old Cakewalk user and I was registered on their site, where I had purchased some products such as Sonar, Z3TA+2 and their other VSTs. Days ago, in my account, I changed the reference email, and in doing so I was waiting for confirmation for the changes I made, but this confirmation never arrived. This way I no longer have the ability to access their old site and so I no longer have access to my products either. Can anyone tell me how to get my Cakewalk account back?
