Check out this thread for info: How to Share Folders (click on link)

If you're still stuck, give us a bit (lot) more info - like what version of LW you use, what OS, what type of files are you trying to share, how do you know the files "not load on 2 limewire"?
Are you trying to find your own files in a search, or have other people not been able to find your files?
What's your firewall status - if LW 4, do you see the firewall icon (brick wall in front of the globe)? If LW 5 tools > advanced tools & there you'll see whether you're behind a firewall & support transfers.
