Another newb with connection issues

[smileychgo]

Hello all. I'm about to throw this pc out the window. I've got a terrible headache now. Okay I have read many of the posts here and I still have no success with Limewire. I have tried EVERYTHING from manually setting a port and configuring my router to disabling/unistalling my firewall and antivirus and still no joy. Even with the settings in my firewall to allow Limewire to connect didn't work. I've also tried the latest version and an old version of Java. I'll provide the requested info that's needed for assistance.

1. OS version? Vista Ultimate with all updates
2. What firewalls you have? Zone Alarm
3. How much ram? 2 gb
4. Hard Disk space available? 216gb free
5. Connection type? High speed cable
6. Modem & router brand name & model numbers? Linksys WRT54G
7. Where are you trying to connect from? HOME
8. What version of LimeWire (LW) & Java do you have? LimeWire Pro 4.14.8 and Java 1.5.0_12
9. Who is your ISP (Internet Service Provider)? Comcast
10. Test DOES work
11. Are you sharing the connection with other computers or p2p sharing programs? Yes - I have another desktop and laptop that also connect to the internet through the wireless router and both run Limewire without any problems.
12. This a new problem with an experienced user.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Yes
14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled? Yes
15. What security programs are you using (antivirus etc)? I'm using ZoneAlarm and Avast antivirus.
16. What country are you living in? U.S.

If more is needed I can provide it. I'm somewhat computer savvy but I can't figure this one out.

Thanks,
Wy
