Enfold Theme Update

Dear Kriesi Team,
I hope you are doing well.
In 2020, I purchased the Enfold Theme and installed it on our website. I recently tried to update the theme, but unfortunately I was unable to do so. I checked my Envato/Themeforest account, but I cannot find the purchase there. I also searched through all my emails and documents but could not locate the purchase code.
Could you please check your database and help me recover the purchase information?
My Envato account has been active since September 2020, so the purchase should have been made around that time.
Thank you very much in advance for your support. I appreciate your help.
Kind regards,
Claudia Aschauer
