When I download a software application for my eMac with OS X and try to open it with Stuffit I have been getting a message indicating that the file my be damaged. Specifically it says that an error has occurred while expanding the file and that the archive may be damaged. This has happened several times from sources. I don't have the "Pro"version of Limewire, do you think that might make a difference. The other thought I have is that the application may have some copyright code preventing it from being copied. Any comments?
