Scheduler warning "The operation cannot be performed" while setting up an Action

Hi, I keep getting an error "The operation cannot be performed" while trying to save an action. The screenshot shows FTP Voyager in the background with the connection open from the "Scheduler Site Profile Manager" and I have full access to the remote site... any help would be appreciated!

(Windows server 2003 sp2, FTP Voyager Ver 16.2.0.328)
