When I attempt to expand password protected files using Stuffit Expander 13.0.3, I get an error saying "An error occurred attempting to expand /Users... The structure of the archive is damaged (error #17540)" I don't however get these errors when expanding files that aren't password protected, they expand normally with Stuffit. I've tried using the Archive Utility.app but it just creates a zip file and creates another rar file. Please help! Thanks in advance.
