Did you start the process by using File->New Resource->New Template...?
Do that, make your template document, File->Save. Now to actually use the template, do File->Template Chooser..., pick your template, and click New Diagram. Immediately do a File->Save to set the filename and location so that there's no issue with that discovered after you've done a whole bunch of work.
Are you by any chance trying to save to a file server instead of a local disk? I understand there can be some issues in that scenario.
