Help!

I am new to Limewire and I need some info.

I keep trying to download songs but everytime I do, I get an error message reading, "Limewire is unable to find a license for this file. Download anyways?" What does this message mean and do I click yes or no?

Please let me know any advice you may have regarding this!

It depends on whether you want to download copyrighted files or not. If you do...click yes. If you don't...click no. How you feel about this will probably depend on where you live & your local laws.
Use the forum search to look for legal, legality, copyright, license or something similar. You'll find heaps of old threads to look through for more info

I'm basically trying not to do anything illegal. However, when I try to find songs that are copyrighted, I seem to have no luck.
