StuffitExpander error?

Hi there, I've tried everything with no luck. I recently downloaded the .rar file of Island Paradise and when I try to extract it using stuffitexpander I get this error

"The structure of the archive is damaged."

It might be worth mentioning too when I try to default extract it I also get some errors. Can't find anything online about this either

Any help would be much appreciated, looks as if I'm going to have to download it again though and my internet connection is so slow

Had the same problem! No one is helping

My connection is not slow. I was able to download IP & expand it with Stuffit no problem. I'm not playing with that EP, but the .rar looks OK to me.
It's possible both your files were damaged during the download. If you were using Transmission (if not, go get it), you can right-click & choose 'Verify Local Data' which would help for troubleshooting.
