Recently installed newest version of L/W and am impressed. Only problem is that I can't seem to get files I successfully downloaded on one computer on our home network to play on other networked computers, nor can I copy files from one computer to another. I enabled the compatability option in the sharing function. Files will open in MMJB for example, and the file will be listed, but it won't play. When I try to copy I get a "check to see if file is write-protected" message. Any suggestions?
