Direct connect problem

[Emmax]

Hi!
I've had problems for a while, I'm not sure where to start, this will be long but I'll try to hand you as much information as possible.

In short terms my problem is when I start LW and click the DC tab i can't get an IP or a box to type an IP into. Instead it tells me a firewall or router is blocking.
I HAVE just recently switched to Comodo(free)Personal firewall and tried to get help there, but they went blank on what was wrong after having me try adding /closing a bunch of different options such as network monitor rules(directed to th right port btw), shutting them off completely, opening the firewall up in almost any possible way, but still LW would not let me have a DC number!

I as a final resolution tried to reinstall both LW and Comodo, but nether that helped!(I could have maybe not deleted the programs properly though, I'm not sure, so that could be one issue but I'm not so sure about if there's any keyfiles somewhere in the system I should find and remove then...)
The weirdest part is that when I just got the FW I added the network monitor rules needed and got it to work in an instant, only for the next time I started LW it did not work, and since then I've had this problem.

But I've been good and read the sticky's first so here's some info for you:
1. OS version? WinXP SP2 most available updates(got some new today I have not installed yet but otherwize they'e up to date)
2. What firewalls you have? Comodo Personal Firewall
3. How much ram? 256Mb
4. Hard Disk space available? hmmm... good question, I right clicked at the C: icon and saw available space 45,7Gb so that should be it...
5. Connection type? Adsl "broadband" (through modem and phoneline) 0,5mb/s I think.
6. Modem & router brand name & model numbers? Don't own a router, modem is a speedtouch something. But I doubt it's important.
7. Where are you trying to connect from? House
8. What version of LimeWire (LW) & Java do you have? LW 4.12.6 Java 1.5.0_06
9. Who is your ISP provider? Doubt it's important but Glocalnet
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 works
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. We only have this computer but I do have other p2p programs such as emule, and bittorrent.
12. Is this a your 1st try at LW or is this a new problem with an experienced user. New problem with experienced user.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? yes


I'm so sick of having this problem ands got a tip of this site from a friend and I hope maybe the problem lise in limewire. But the port it is not since it works in the above test and it's never failed before, and I even switched ports to try that too but it didn't work then ether.
One suggetsion i have is that it's something with the proxy settings. But I'm not so sure what a proxy is so I don't know what the settings should be.

Any help, or any small tips even would be so greatly appreciated.
Thanks!
