Hello all! Desperately need help. I have bought a used MBP 15" and am using my 30,000+ songs for iTunes on a LaCie 500GB external HD. I am a DJ and really need to get this HD talking to my new MBP. I try to do the OPTION and sign on iTunes thing, but when I try to choose a library, it says "An iTunes library file could not be found in the folder 'LaCie 500GB. Please choose a different folder.'" Basically, I just want to use the external HD on the new computer as my iTunes library storage. Any advice is greatly appreciated.
