Hi, I have a big problem. I moved my i Tunes Library to an external hard drive. upon cleaning out my computer harddrive I found my old It tunes library folder and moved it onto my external HD. the prompter asked me whether I wanted to cancel the transfer or replace the existing folder. I accidentally pressed replace. Now I can't find my song files. Are they gone forever? Has anyone ben in this position before? Any advice is appreciated. Thanks, M
