Unable to Upload
 

I have no problems downloading stuff via Limewire, but feel slightly guilty as i cannot upload hence am unable to share any of my own files. The only bit of information i can find which may be connected to this problem- when i click "show incoming searches" in monitor- is Limewire telling me that my "client is a leaf node shielded by an ultrapeer". I have absolutely NO idea what this means in any case- can someone tell me????:mad2:
P.S. i run on OSx 10.4.11 (Tiger)
