THe Files are getting deleted from Lime Wire itself. From LIme Wire in general!! I have The Basic 4.10.0 and i got it from the offical website!! I do have a AV program and i have run it lately. Its been happening a while now!!! i first noticed it when i tried to play a song on iTunes and it said that the file was missing so i looked on lime wire and it was gone!! and the files were real!!
