Sorry it took me so long to respond to this post ~ I have been working ridiculous hours so in any case, here are my system details as per the link you sent me:
1. OS Version: Windows Vista 2007
2. What firewalls you have? : McAfee (came pre-installed)
3. How much ram? : I am not sure, I don't know how to check it
4. Hard Disk space available? : I am not sure, I don't know how to check
5. Connection type? (eg: dialup, broadband, cable, etc.) : cable hi-speed
6. Modem & router brand name & model numbers? : Modem is a Motorola SB5100 / router is a Netgear Rangemax Wireless Router model # WPN824v2
7. Where are you trying to connect from (house, appartment complex, school, student accomodation, work, etc.)? : house primarily, but at work as well (which is a hotel)
8. What version of LimeWire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version. : I uninstalled LimeWire because it was trying to connect every time I turned on my computer, and then the connection speed to the internet was zero
9. Who is your ISP provider (Internet Service Provider)? : Comcast
10. Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say 'Your test worked!'. What happens when you go there? : It says "Your Test Worked!!"
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. : NO, not at the same time that I am using this laptop. The reason being the other computer in my household is a 98 HP and it cannot connect to my router. So in order to have my computer work, the other cannot be online and vice versa.
12. Is this a your 1st try at LW or is this a new problem with an experienced user. : This is my first attempt at limewire with my new computer, but I have used LW many times with other computers before.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? : Because I uninstalled the LW program, I no longer have a LW icon.

So there are most of the questions answered, and I will be checking this post again for your answers. Thank any and all of you that have volunteered to help people like me
