License key not found when trying to cancel subscription

Hello, I’m trying to cancel my subscription, but every time I enter my license key in the link, the following message appears:

“Oops. We’re not able to find your license details right now.
Please contact support for more information (and show them this message so they can help).”

I am copying and pasting the key exactly as it is shown in the program, but it still doesn’t work.

I’m unable to manage my subscription in any way.

Are you using this page: Subscription Management

It asks for your email address and your Cleverbridge Number not your licence key.
If you don’t still have your purchase email which has the Cleverbridge number then you can also look it up here:

If it isn’t that and you want to contact CCleaner support then:
All customers MUST now use the ‘Live Chat’ support service. It is currently the only way to contact support.

To start the support process fill in this form: Contact Form.
Once you click ‘Next’ to submit the form you will be given a support ticket/ID number onscreen, with a summary of your request.
The 'Live Chart dialogue should open automatically with a message from the AI Chatbot - if it doesn’t open itself then there is a ‘Start Chat’ button.
If the Chatbot can’t help then you will be passed to a real person.

IMPORTANT- Don’t just fill in the form and leave - If you do not engage with the chat then you will not get any reply.

If you are still not having any success then @Laurence_CCleaner should be able to help here on the forum.
However it is the Easter holiday weekend now and he may not be at his desk until next Tuesday.
