From the document you posted it seems that your Windows configuration is hiding extensions for known file types. You should be saving your template as an Excel Template file (.XLT) not an Excel Workbook file (.XLS).
Excel 2007 has several Save As Type options. When saving as a Template you should select "Excel 97 - 2003 Template (*.xlt)". This will force the .XLT extension which is required by Stardraw. Other template types use different extensions, e.g. .xltx and .xltm, and these will NOT be recognized by Stardraw.
I hope this is helpful. Kind regards,Rob RobinsonStardraw.com
