skype for business has stopped working

I also have the same problem. I upgrade the Lync of MS Office Professional Plus 2013 to Skype for Business. But when I try to run the application, it stuck in "Welcome" just like the screenshot above. But you can still use the Skype for Business unless you don't close the "Skype for business has stopped working". 

I tried to uninstall then reinstall the Upgrade for Lync. I also tried to uninstall then reinstall the whole MS Office but nothing works to remove the error dialog box "Skype for business has stopped working".
