Well, I think I did everything right and every file is where it's supposed to be. But when I try to run the .command file to initialize V4.2, I'm told I don't have the correct permissions to run it. I checked the permissions on the file and I do, indeed, have full read & write permissions, but it still won't run. Just for kicks, I made a duplicate of the file, and that actually opened and ran in Terminal. But the operation will not complete. It gets most of the way through and simply stops. I've re-downloaded the file a couple of times, cleared everything and started from scratch, with no result. Have to admit, I'm running out of ideas.
