weel i updated my java and no luck, and I am 100% possitive that its not my ISP becuase not only does it work when i plug it into my other computer right beside me, my friend has it running 2 houses down on the same internet.

Im starting to think theres like a security pack built into windows or something. if not is there any program I can use to see WHAT is blocking it if it isnt my ISP?
Im beggining to think I will never be able to use P2P again....
