Awaiting sources usually means that you havent connected to a host with the file your after, your best bet is to dl the file with the largest amount of hosts(the number beside file name) if you get the same result it would mean that a large amount of people are after the same file and you have to wait your turn, but more than likely the host with the file your after may not be online if your been waiting days for it, delete it and search it again, remembering to go for the biggest number of hosts....

I hope this makes sence, its a bit early lol
