o yea and i just downloaded iTunes on my iMac and its not working. no real icon came up, just a blank document icon and it said try opening with: stuffit expander or movie player and i tried both and neither worked. i tried the same thing with the virus protection software agax today and the same thing happened. i was deleting old things off my harddrive today so do you think i deleted something very important that will open these downloaded programs. if you know please tell. i was only deleting stuff i already had copies of though im pretty sure
