For about 1 month limewire disappears off my desktop and I have to go to C: to limewire.exe to get it to start. Today when I did that it opened but all the songs were gone. I found them on itunes but don't have a clue how to get the songs back to limewire. I'm thinking I will delete and download limewire again but still need to know how to get these songs from itunes back to limewire. I appreciate any input and thanks for your time.

Run chkdsk/f from the command prompt, and reboot, probably have a disk error.
