I have an ASL app that seems to be having issues with remembering that it already has videos downloaded. Their support is pointing the blame on CCleaner yet I haven't run CCleaner after the last time I downloaded their videos. I was under the impression that CCleaner only cleaned when I ran the app and then told it to clean after the analyzing. Does CCleaner run in the background and do automated cleaning? I guessing no as I have not set it to do so but I need a clear answer before I hit their support as this is the third time their app has done this, which is why I haven't ran CCleaner since re-downloading.
