There are likely some changes you could make to your java.policy file to resolve the problem.
Search your c: drive for a file with the name java.policy and add the following:
grant {
// permissions to resolve and connect all sockets
permission java.net.SocketPermission "*", "connect,resolve";
// permissions for RMI when using appletviewer or Java Plug-in
permission java.net.SocketPermission "*:1024-", "accept,connect,listen,resolve";
};
I make no claims about your system security after making this change. There are probably more restrictive settings that would also work, but I'm lazy.
