I can't load the new LW upgrade to my Mac, either. I managed to get a disk image, but get an error msg about not having permission to replace the LW, even tho' I'm logged in as root. I tried another download of Pro ('cause I paid for it a while back) and got gibberish text instead. Now I can't even start the old LW... it just quits. Help!

I did upgrade to the new and buggy Mac OS X upgrade. I learned never to do that again w/o giving it a few days to simmer. Wonder if that's the problem.
