Download file is not valid
 

I'm currently using Win XP with the latest version of limewire. My original file, I was D/L to, was limewire shared. I shut my computer down for the night and the next day I went to use limewire, I got the message that file was not valid and I had to pick another download file. I did and I was able to download and play my music. I repeated the above process 5 times. I would pick a file to D/L to and the next day I would get the same message. The other users on the computer have not had this problem. I am the only admin level person on this home computer.

Make sure none of LimeWire's files (especially not the files in the 'Incomplete' directory, the 'Shared' directory and both directories itself) are write-protected.

How do you know the file is write protected after you download it. I did notice that there was album art in the file, but I dont know where it is coming from.
