Need help canceling my ccleaner professional trial.. when i hit manage subscription on ccleaner professional, it says enter email address and reference #.. i never registered for a account or I totally forget which email I’ve registered with as I’ve checked every one and found nothing. it says auto renew - on and I have no way of canceling my subscription. how do i find out what email I registered with. And if I did not register with any email how do I go about canceling my subscription? PLEASE HELP!!
