Data lost on Document area

[offtheroad]

I lost about 130GB of video tutorials that were in my Documents area but the space is still being used some where. Yes I checked the trash. I'm on a Mac Pro Intel Snow Leopard 10.6.7
I ran DiskWarrior 4.2 and it said I had Propety List damage and could not be repaired. See attachment.
Thanks
