Reloaded XP, can't find files!!

[atx85]

I had a bootleg copy of Windows XP. I loaded a new copy and lost everything because I did it wrong. I took it to a pro and he fixed it. I had to reload a lot of programs but they all still picked up the old files that were relevant to them. However, when I reloaded Limewire it would not pick up all my songs I had downloaded before. The only thing there were some saved playlists. I'm pretty sure they are still on my hard drive but have no clue on how to retrieve them. I would appreciate any help. Thank you.
