It says that the download code has already been used. How do I do it?

I bought this product.
I clicked “Delete” on the wrong page.
Cubase 11 disappeared in my product.
So, the download access code…
I re-entered it.
Download Access Code is already consumed by another user. Please contact your local support team. There’s a sentence. How do I fix it?
