DRAKEMATA I am looking into the permissions error right now. I had tested the program on all of my machines (all running Leopard, with different user names) with no problems so this is something I wasn't aware of.
As for the upload not working, please make sure you have your CONFIG file correct. The "remotedir" should be formatted exactly like the example (i.e. no preceeding "~", just "/your/remote/dir". Please let me know if that fixes the upload problem.
I am also currently working adding a notification in case of any errors.
