I can't find the firewall tab (or anything in general about it) in my sharing section of system prefs.

To the other methods, I've dumped about 100 song back into shared folder (the only reason there were so few was that I had iTunes that copies the files so I no longer needed them on LW). Incompletele cleaned out incomplete folders....but still not one stable connection.

Another thing, about 2 weeks it was working...in fact working wonderfully...with like 6 connections running at a time. I don't usually put up more than 4 searches at a time also...I hope that helps in narrowing it down. I have to try to install it again..but I tried that last week and still had no luck.
