Gnutella Forums - Unable to connect even after reading and using sticky post guidlines

Hi Folks! I am new to this forum and will try my best to give you all the information you require. I simply cannot get my Limewire to connect even though I have read and tried most of the suggestions found in the 3 sticky posts at the top of this connection problems forum. The suggestions I have not tried are the ones that I cannot understand i.e. too technical. Anyway here is the info below:

1. OS version? Windows Vista
2. What firewalls you have? Zone Alarm Free
3. How much ram? 1GB
4. Hard Disk space available? 110GB free of 149GB
5. Connection type? (eg: dialup, broadband, cable, etc.) Broadband
6. Modem & router brand name & model numbers? D-Link DSL-G604T router
7. Where are you trying to connect from (house, appartment complex, school, student accomodation, work, etc.)? House
8. What version of LimeWire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version. LW 4.14.12 Java 1.6.0_03
9. Who is your ISP (Internet Service Provider)? PlusNet
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? Page works fine
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. Network of 2 other PCs in house. No other P2P programs unless iTunes counts as one?
12. Is this a your 1st try at LW or is this a new problem with an experienced user. 1st try worked fine, cannot connect again
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? _ click here to see Sample image Yes
14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled? Port forwarding as far as I can see, not too sure
15. What security programs are you using (antivirus etc)? Some people might not be aware that their security suite includes a firewall http://www.gnutellaforums.com/connec...lies/smile.gif Using AVG Free and Comodo BOClean
16. What country are you living in? Sometimes there are ISPs with the same name in more than one country (eg Clearwire in the USA & also in Ireland). England, UK

Thanks for looking into this.
