hi i have or used to have limewire =/

basically my limewire was workin fine las nite and when i switched my pc on this morning i double click my limewire icon on my desktop and i get :

"the item limewire.exe that this shortcut refers to has been changed moved etc " its basically jus disappeared or deleted itself somehow??

i checked my programs dir to see if limewire was there and nothing the folder was gone!! Also cheked my recycle bin and nothing no trace of it =/

i dont understand how limewire jus deleted itself???

Has this happen before to anyone?? im so confuseddddddddddddddddddddddddd =(
