Never had any real problems apart from sometimes during updates it wants to install Some sort of Their Rubbish, ALWAYS click Decline anyway.
The Latest version is 6.34.11482
Sometimes if a program plays up you have to fully uninstall it before reinstalling, I use Revo Uninstaller (Free) in advanced mode, this lets you remove the registry Keys and left over folders as well.
I do find Ccleaner gets more than the inbuilt Microsoft Cleaner, especially temp files.

Upgrades = Old bugs replaced with new Bugs.
