Downloading CCleaner Updates (newbie)

When I first downloaded CCleaner, I donated $20. as suggested. When I run CCleaner, it keeps saying there is an update ready (I have ver 2.09.600). When I tried to update to 2.10 it brought me to the donation screen. Now again when I ran the program, it said there was an upgrade 2.11. When I clicked the link, it brought me to the donation place again. Am I supposed to be donating $20, each time there is an upgrade? I wasn't able to find any info on this here. Thanks in advance for help.

Where did you get CCleaner from?

This is the page it shows me when checking for an update on the official website:

Also, a donate is just that a donate it is not paying for the application, the application is free. That said that is awesome that you donated, very few people do that for freeware.
