need help retrieve a Cubik Pro account that is linked to a deleted email [Solved]

[GO2GULAG]

i know that this is quite a complicated situation and i wont be dissapointed if it cant be resolved but i still wanna give it a try,

i originally bought Cubik Pro many years ago and linked it to my secondary gmail, the problem is that, when i tried to download it to use it for 3d texturepacks in minecraft again, I realised that i had deleted my secondary gmail account a few years ago. However when i try to use the forgot username option and enter the now deleted gmail account, it still says that it was a sucess and that an email has been sent, but i can of course not check my inbox anymore because it doesnt exist anymore

is there any way for me to prove that it belongs to me?

the secondary email was called [email protected]
the primary one is called [email protected]


thank you in advance

the account im using to post this is my primary email by the way

You will need to send me some information via a Private Message:

• Your real name (or the name of the person who bought Cubik)
• Your username (if it was previously something else)
• Your receipt (or a reasonable estimate of the date of purchase)
• Your Cubik serial (if known)
