Hello and Welcome to the LimeWire forums!

You might not have setup LimeWire to share your music. To share files, you need to go to the menu bar in LimeWire and click Tools then come down to Options. When the Options window comes up click sharing, then click the browse button to choose the folder of music you want to share.

WARNING: Do not share your entire hard drive or your whole computer may be exposed. Only share files which you want anyone in the world to see.

You can share files other ways than the one I mentioned. <http://www.limewire.com/english/content/faq.shtml#fil1> I hope this solves your problem.
