New document, open document and some commands in task pane doesn't work.

Hello everybody,

I'm using Solidworks 2015 SP0, windows 7 ultimate.

I can use the New Document comment in "File" or press "Ctrl+N"

But when I clicked on those commands on task pane, nothing happened.

Does anyone face this issue ? Could you please help me ?

I tried many ways on Google to solve this, but I still cannot find a right solution.

Thank you very much
