These new licence key formats do need a recent version of CCleaner to run. Worse, the CCleaner EULA warranty language extends only to 30 days from the date the license is issued, regardless of whether due to their own bug the software license provided doesn't work. I'd contacted support a couple weeks ago about the constant nagging as well regarding license keys being expired, support could see the new key but it doesn't show up if I request my license keys via the web and doesn't work in the actual application. In the expired license dialog the prompt for a new license accepts only licenses in the old form. Additionally the format of the new license key is different from the old - the new one is XXXXXX-XXXXXX-XXXXXX and the old format is XXXX-XXXX-XXXX-XXXX-XXXX.

Requesting my licenses only shows my past expired licenses and not the license purchased in October under the same email address. The license I bought in October doesn't work, I can enter it and ccleaner says it's registered but every time I restart it says the key is invalid and it reverts to free mode.
