When I went to my Library all my music was gone and I didn't have a completed folder I just had an incompleted folder. Then when I tried to download more music it finished the download but when i went to play it in my library it was gone. So any files I try to download are just gone

I can assure you your files are not 'gone!' They are on your HDD somewhere! Check your Saving folder settings. Go to your LW menu Tools-Options & Saving. This will tell u the name, location & path of your LW dwnld folder (remember that once a file has completed dwnlding, LW transfers it from the incomplete folder to the dwnld folder.) Rather than I explain it for the xth time today see this thread! (Just click on the link.)

For more details how to setup a shared folder see this other thread!

Good luck & hope this helps!
