Never had a connect problem with a PC but.........
 

With this MAC there is no connecting, WHY?
Macintosh PowerBook G3 Wallstreet 266 connected by ethernet to a 5 port switch (no firewalls hardware or software). This switch is connected by ethernet to a motorola cable modem ( supplyed by road runner. I've gone thru the entire help list trouble files (extremely vague by the way) no help. My IP is 24.208.15.253 assigned by DHCP, running Internet Explorer Mac 4.1. Gnutella is recognised and allowed by my cable service. My connection is working (I'm using it now). 10 hosts are showing (connecting ) and have been showing (connecting) for 2 days 11 hrs and serval minutes which will have changed as I type. Protocols are listed as 0.6 and ultrapeer, the search buttons are grayed out (any type,programs, video, ect.), and there is a green button at the bottom left corner. File is on search and it is the latest Lime wire (I down loaded and installed it seven times using the defaults offered). I've never had a problem on any PC, is it my Mac ? Thanks

I dont think its your Mac coz im having exactly the same problem, and it looks like loads of other people are on this site as well. Wot version are you using coz i am able to run it in OS9 but my OSX version will not connect, it connected for 2 minutes when i installed it but then disconnected its self and never came back on line, so im not to sure wots going on.

If you can't connect to gnutella, you connection doesn't allow you to do so. ISPs can't block gnutella connections rather easily.

You might also have frelled your connection settings, so LimeWire cannot connect. There are no known bugs in the connection code - if there were any they would appear on all plattforms.
