remote connection

Hi
I have searched high and low for an answer to the following problem but still can sort it.
I have been using subsonic for sometime now and until a few months ago I could connect remotely. Then all of a sudden I couldn't connect.
It used to connect to the port automatic but now I get the mess "failed to create port forward. see log for details"
I have tried to set up manual but get the message "port forwarding disabled"
I have checked to port 4040 and it is open.
Please help as I love subsonic but will have to look else where if I cant sort the problem.
Thanks
