Itunes 8.2 Playlist gone after installing Itunes 9 and reverting back to 8

Help! My computer installed Itunes 9 automatically. I hated it and deleted Itunes 9, reinstalled Itunes 8 went to my Previous Itunes Libraries and moved that to my new section. Itunes 8 now opens with my library but all of my playlists are gone.

Try to find the .xml file located in the music folder and use the itunes import playlist function.

Hope this helps.

Thanks. I tried that now, but it doesn't pull it up. Any other suggestions? I had tons of playlists that took hours to create.
