SolidWorks 2015 not responding

Hi, everyone

I was using a student version of SolidWorks 2015 for the last month, everything is OK till yesterday.

When I open the program and click 'new' - 'part' or 'assembly', this program freeze to work. The task manager shows 'SolidWorks not responding', I can do nothing except forcing it to shut.

Actually, before I start 'new' project, I can click almost anywhere, like 'options' or close the window.

I googled 'solidworks freeze' issues, tried to re-install the program, refreshed the registry and windows updates, yet none of them worked.

I am using WIndows 10 64bit.

Somebody got a hint? Thanks for your help.
