Has ccPortable (aka CCleaner) become payware?

Has CCleaner (ccPortable from Portable Apps) has become payware?

Until recently I had no problem running ccPortable on my Win 10 home.

When I click on 'custom clean' I get taken to a page where there is an offer ('use Pro version for free for 30 trial days') which I cannot refuse. Not accepting the Pro version means I cannot proceed with the cleaning. I'm blocked. Accepting the offer means I have to submit my Visa details to CCleaner, even if on a temporary basis ('30 day trial').

Is there any way around this, short of unstalling this now disfucntional software?
(Note: Other ccPortable features work fine e.g. Registry cleaner, Tools etc. But the main function 'Custom clean' refuses to run without a commitment to payware.)
