lol, that's too priceless, the click on the blue link comment. It saddens me that people who don't know what a hyperlink look like are trying to D/L w/ limewire. Anywho...

1. OS version? Vista
2. What firewalls you have? Windows Only
3. How much ram? 1918MB (2k)
4. Hard Disk space available? 106GB/184GB (200GB)
5. Connection type? Comcast Cable
6. Modem & router brand name & model numbers? Modem - Comcast; Router - Belkin 54G... Forget the rest, but it's never caused issues before.
7. Where are you trying to connect from - Home/House
8. What version of LimeWire (LW) & Java do you have? Since I uninstalled Limewire, I'm not sure how to check my Java. I originally had a pretty old version of Limewire, from about a year ago, then I downloaded the newest 5.x one directly from the web page today to try that one as well, and I tried Frostwire as well today, also the most recent version directly from that web page.
9. Who is your ISP (Internet Service Provider)? Comcast *bleh*
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? 'Your test worked!' loaded immediately.
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. One other new wireless set up less than a week ago and one wired, issues occured on new pc but not on old one while LAN was connected, no new issues have arised from the new WAN.
12. Is this a your 1st try at LW or is this a new problem with an experienced user. No I used to use LW a lot on quite a few computers in my day, this is the first one I've had a problem with, also coincidentally the first one with Vista.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Yes I saw the brick wall and I could've sworn it was there but in a different location after installing the brand new LW 5.x today, I thought it was up top for some reason, perhaps that was Frostwire.
14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled? Both maybe? I could probably figure out where in my router settings it was if it wasn't such a sucky, tiring day. I thought UPnP was enabled but I play WoW and they've had me set up specific ports to keep open and listen on?
15. What security programs are you using (antivirus etc)? AVG Free only - I've tried disabling this as well.
16. What country are you living in? US of A
17. Has anything in your setup changed recently? Have you updated your version of LW or Java? Have you added any new software or new hardware? Have you updated any software? Have you moved house, changed internet plan or ISP etc etc?
The only thing that changed that caused the problem was getting a new laptop with Vista, until that point, it worked fine on my old laptop. I've attempted to make various other changes by disabling things and allowing things and updating things to fix the problem, none have worked.

Hope this clears up everything you need to know, I will check out the second blue link tomorrow during my lunch break from work and respond to any responses then as well. Or maybe if I have a little time before I leave for work in the morning. Have a good night and thank you.
