I had issues with 2.0 so I down graded to 1.1.4. I needed itunes 7.5. I deleted itunes 7.7 and I am now running 7.5. How do I get 7.5 to find my music now. I saved the library file itl file. I tried replacing the other file and itune tells me my old file is saved for a newer itunes. Can I not use my old itl file?
