Trouble decompressing file

Hi Kari,
Is there a chance that this error cropped back up again? I have tried downloading my .dat file a couple of times and every time I try to unpack it I get Error 79 on my mac. I also tried unpacking it in the terminal and was unsuccessful there as well. It’s a small extract, so I don’t think it’s a file size issue. Just trying to figure out what end this problem is originating from!
Thank you,
Kate
