I have the same problem with .sit files mysteriously ending up as limewire documents and I am not able to open them!!! It's so frustrating!. I downloaded the MP3Rage and that isn't working. When I drop the file onto the MP3 Rage, nothing happens. I can't find it browsing through my files although I see it on my desktop clear as day. It's like it's invisible!!

I am just confused and frustrated. Someone please help! Why doesn't this work? I have had this problem many times before.
Thanks,
Gabrielle
