Gnutella Forums - Limewire Start-up problems again, old fixes not working

Well, did post in the massive 80 page long thread, been told to make a new thread for myself. Basically, when i try to load limewire up, the box that appears in the middle of the screen appear, but then closes 2 seconds later and limewire never loads up. My set-up is

1. OS version? (eg: Windows 98) Windows XP
2. What firewalls you have? Norton
3. How much ram? 1 GB
4. Hard Disk space available? Around 30GB left or something
5. Connection type? (eg: dialup, broadband, cable, etc.) Cable, currently getting around 8MB
6. Modem & router brand name & model numbers? Modem is a Webstar and my router is a Netgear. Couldn't tell you the model numbers
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. Limewire is 4.12.11 and Java is 1.6.0_01
9. Who is your ISP provider (Internet Service Provider)? Virgin Media
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!"
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. Nope
12. Is this a your 1st try at LW or is this a new problem with an experienced user. Had limewire for years now, had this problem before, and did your recommended fixes which worked, but now, there is no .limewire folder for me to delete in my documents and settings this time round.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Don't get that far :P

Anyway, my guess is that the lack of a .limewire folder to delete is stopping me from fixing this, but the strange thing is, limewire just decided to stop working one day, having already been on in the morning, i went to go on in the evening and it wouldn't load.

Any help is much appreciated.
