Hello,
I'm trying to install a sit file and keep getting a file expanding error cs.4.rar format error #17540. I have osx, the downloaded file is osx and I have the latest version of stuffit. I have been trying to expand it from my shared file rather than Limewire and have moved everything to the desktop to no avail. Additionally, this has happened with two separate downloaded files of the same variety. Not sure what to do.
