ok.
I used to have a song by Ian Van Dahl called "waiting 4 you" on my music program. (Napster) But now for some reason, whenever I want to play it, it just tells me "Sorry, this track is no longer avaliable unless you buy it. Please sign into Napster, locate the track, and buy it." Ok, I already bought the song, I've gone back to where the track is, tried to play it, and it doesn't work.
Soo... I tried to download the song off a different program, but it doesn't have the track. I've been looking for some time for this damn song, but I can't find it....

Does anyone here know where I can get the song?

I use Limewire and get all my songs for free. But, if you choose to use Limewire (if you haven't tried it already) make sure the files you're downloading are actual MP3's because that program is VERY prone to viruses. If you're a mac user, Poisoned works also, and it's not as susceptible to viruses (although songs are harder to find).
