Sorry it took so long to back to you. I'm working 13hrs a day this past week. I'll answer the questions I can. And thanks for help!!!

1-windows XP
2- I already followed the firewall configuration, so tha't done.
3-RAM ??? Not a clue
4-Disk space, again Not a clue
5-DSL
6-Modem and router brand and #'s, again I don't know. I'm new at all this, p.c stuff.
7-connecting from home
8-LW version 3.0.2 was working, before I updated to the new version offered. That's when everything went to S- - - ! I uninstalled the new version and went back to the 3.0.2 and it doesn't work any more. "By highlighted" search button, I meant you can tell when a button is giving you the option to choose it by the way it looks. Prominent or black for a usable button and then the shaded, pale grey "not highlighted" when it's not an option. Does this make sense??? I tried as you suggested, hitting the enter key on my keyboard instead of the search button on LM. Still, nothing.
9-ISP Bellsouth
10-Not sharing the connection
11-Did the test http://www3.limewire.com:6346/ It said the test "worked".

Hope this info, as limited as it is, "helps you help me"

Thanks again for "all" your effort. I appreciate it
