absolutely cannot get songs to launch

I am really frusterated. My limewire was working fine, I just double-clicked songs after I downloaded them and they would automatically go into iTunes and play. But then my internet and limewire were messed up for a while (kept freezing, etc.) because of a power outage, and now I can't play songs. I can download them, but when I try to launch them by either double clicking or pressing the button, absolutely nothing happens at all. I have read all your advice and nothing has worked. I cannot drag files out of my library into the iTunes associator thing, in my apple control panels, all mp3s are set to itunes, and I have gone into my itunes file menu into general and pressed the set button. NOTHING!!! no matter what I do I cannot get it to launch, when I press the button or double click its like I did nothing, it won't respond.
I am frusterated to the point of tears. I just CAN't get it to work and I don't know why!!! please please please help me!

I feel your pain, I'm done with this piece of **** app, I've been with it since 1.7, and hardly one thing has improved, Harvard Boy needs to go back to school and get a little more knowledge, as for me and if you drop me a line, a hacker friend of mine showed me the most wonderful , and private file sharing app to date, puts this dump bucket to tears, Kiss My Mississippi *** LimeWire!
