Connection Problems,

Im also experencing simmliar problems connecting with any of my p2p programs. All Kazaa, Limewire, Morpheus all seem to not want to connect. When I open limewire like everyone else the light is green for about 1/2 a second then goes red, and if i go to the connections tab, i see all the connections trying to connect then they 1 by 1 just dissapear untill there all gone and it dosent even try to connect. Ive tryed a few things like different limewire connections, such as connect3.gnutellanet.com and still nothing. Im using Limewire 2.4.2. Also when I try and use the older verson 2.1.3, I click on the icon and it the mouse icon says its loading then it stops, and if I hit CTRL ALT DELETE and look in the programs running, it says Javaw at the bottom and dosent load. But if I then click on the icon again it actully starts to load but it loads both of them. If i try to wait for the first one to load before trying to open it again, I just stalls, I left my computer for about a hour and it dident open... Limewire and Kazaa seemed to work exallent for me, then one night i tryed to log on, and it wouldent connect, then i tryed Kazaa, same problem, it just says Connecting... at the bottom and never connects. Im running a firewall, but Ive even turned it completely off and all the programs still wont connect. Id like to know if there is just problems with the servers or something so I know whats wrong with it... I hurd some things about use other ports or do something to see if my ISP is blocking the connections, can someone explane to me how i can go about doing that, and what other ports i should use stuff like that.
Thanks,
Brandon
