I am using CCleaner PRO at home with an annual subscription which I have renewed year after year and this is a NEW problem. Have installed all updates available and now when I do a Custom Clean - which includes a checkmark under System for Empty the Recycle Bin - the Clean does not empty my recycle bin as it has in the past. Thank you for any suggestions to fix this bug.
Your bin may be corrupted, see here
