I received a weird email apparently from Piriform saying my CCleaner license expired months ago, but I don't think it was that long ago that I bought the pro license. See screenshot Is this legit? The CCleaner install running on my machine doesn't saying anything about the license being expired, I checked under Options>About and it looks valid to me.. I didn't go to the page of course but I'd like to find out if my license is actually expired so I can renew it.
