Hello, I have had Limewire for about two years now and don't have any problems.
When you first installed the programme it will have taken you through a set up procedure and will have asked you where you wanted the files to be stored. you should have named a new file say "recieved files" and told Limewire to send them there. I do this and then when i have listened to the file if i like it i "drag" it to another Folder where i keep all "my Music"
Try to name the files correctly then the comp will keep them in strict alphabetical order and list them as such....very easy to manage them this way.
If you have lost the files Limewire will have saved them somewhere so use the Start menu and search for them. you can then re-name the folder and use this as the "holding folder" for your music.
I hope this has been a help to you .
But please make sure you configure Limewire to share your "my music" file. Chris
