my main computer is an intel imac running snow leopard. i recently bought a mac mini running lion for the "family" computer. i wanted to put all of my itunes music from my imac into the mini via an external hard drive. after loading all the music into the mini, i keep getting an error message stating that "the original file could not be found", so obviously i did something wrong. i've done this before w/other macs w/no issues. not sure what happened here, but could someone enlighten me on the proper way to do this? thanks!
