somebody help!!!!big problem!!!what's this lock i found in my limewire window??
 

hi..can you help me with this??

ever since i download the latest version of limwire i can't download songs anymore even though i have java downloaded in my program.

when i open the limewire window,it looks it functions,for i can view the menu and stuff like that,but when i tried to SEARCH for SONGS in order for me to download,no search results appeared..i only saw a message on the upper part of the music search window,below library button having this "(triangle sign with an exclaimation point on it)ONLY SEARCH RESULTS WITH A (lock sign)ARE OFFICIAL LIMEWIRE COMMUNICATIONS" .....thats it..and i dunno why no results are being shown..

ALSO:
when i open the limewire program, i read this pop-up msg "limewire was unable to set you a port to listen for incoming connections......."

what will i do????????

pls help me..ive been trying to figure this out for like a week already..and nothing's happen..
ive been re-installing the limewire and the java program..but still no change..

pls..help..thanks..
