Forgive me if I'm missing something obvious... I read the new features of v5.0 with some excitement when I saw that it was going to manage Google Chrome plug-ins. Mine need some help. But, I haven't been able to find where it happens. Can anyone point me in the right direction please?

I subscribe to the Rhapsody music site and listen to the music from this site daily. I run CCleaner every Thursday. Every Thursday, three of the things CCleaner wants to remove are "Unused File Extensions" .aac, .ra, .rax. Every Thursday I let CCleaner remove them and then they are back the next week. I'm fairly certain these extensions are related to Rhapsody. Is this a bug or do I just need to do something different? Any thoughts are welcome.
