Shoutbox

The "Transfer Canceled" message appears in one of these cases:

1) The user canceled the transfer (which is not your case)
2) The client (receiver) could not connect to the server (sender)

Please verify if the sender's IP Address is correct in the message that appears when you send a file, and if the sender has that port opened for TCP traffic in the firewall. If not, go to the plugin options and change the settings there.

If they're correct, then I ask you to tell me your operating system and Messenger version so we can track down the problem.
