I have used CCleaner for years. I have the $49.95/year account. I have two new computers. I can't install CCleaner. It asks for license number but says invalid. i need to install or close my account. It was paid up in February, 2023. Please help. I have a new e-mail address. Old e-mail address is dead. I need someone from CCleaner to fix this or close my account and refund my money to spend on other software.
