all my songs have dissapered

[becks88]

i went to go in to limewire today.Insted of it loading up as normal i was asked to choose a language and a few other things,it looked a lot like i was installing it again,but i wasnt,it has already been installed.

when i had gone through the process of choosing the language and the file name it would go under, it opened up.And all the songs that had previously been downloaded had dissapered.

please help.

the previous night my mum didnt shut the laptop down correctly,she just pressed the power button until the computer turned of,could this have affected it in anyway?
