I don't know Cleverbridge reference number

I’m having trouble figuring out the Cleverbridge reference number.

You may have entered the wrong address when registering.

I know the license key, so I would like to know how to solve it.

The Cleverbridge number should be on your purchase confirmation email.

If you no longer have that then you can lookup your Cleverbridge reference using the lookup tool here: Customer Support Contact Page

You may have entered your email address incorrectly.
So I don’t have any email.

I’ve bumped this for the attention of the CCleaner staff.
