Hi, I'm an experienced Mac user and something is stumping me. After downloading some .sit files and opening them with Stuffit Deluxe 6.01 , I get what looks like binary data. Do you have to hit the "launch" button on the LimeWire screen? Plus, the creator of the files are LimeWire. This is what "file buddy" is telling me. What is the proper way to unstuff a .sit file after downloading? Any help would be greatly appreciated. Thanks.
