Open/Save file

I am using SolidWorks Professional 2013 SP 2.0.

When I try to open a file in SolidWorks nothing happens and also when I try to save a file nothing happens.

I have tried to repair the SolidWorks but still the problem persists.

I dont want to reinstall my software.

Kindly reply with a solution.
