Unable to activate or open solidworks costing template

hi, there
I'm trying to open solid works's costing template but software isn't giving any response,
When i access the soil-works costing from evaluate tab, then it shows a tab in the task pan but with empty in it
even i tried to open it from the "Costing template editor" but still no windows appears?
I'm attaching a screen shot, if you know or got my problem, please help me to get out of this
thanks
