Port open, still can't connect by IP

Title: Port open, still can't connect by IP

Version: 0.5.1

OS: Windows 7 Professional

Java Version: 6 update 30

Description of Problem:

Since installing .65 I can't by IP despite the port being open. I realize my Java version is old, but I only want to update it as a last resort, as this will take hours I don't have (simply installing the new version makes my computer claim to see the old one, despite a restart).

Error Messages:

For some reason these aren't saved in serve log either:

NM, solved the problem. Router was no loopback, but people from outside the network can connect with the IP just fine.
