PsmDeviceForUnity has stopped working...

I get this error EVERYTIME I try and use the Publishing Utility for Unity and select Key Management from the left. I have uninstalled the utility and Unity PSM and PSM Dev for Unity on my Vita numerous times and rebooted and reinstalled. I have scoured the internet looking for others solutions and I have found none.

I know the drivers are installed correctly because I can see the Vita in Device Management and when I start PSM Dev for Unity on the Vita Device Manager sees the Debug part as per Sony's troubleshooting so I know all is good there. I have never been able to see the Vita in the Publishing Utility for Unity so I am not sure what the issue is. I just know that anytime I go to the Key Management section or Unity Build gets to that point I get a PS<DeviceForUnity has stopped working error.

Can someone please help?

 

Ok I had your same problem like 5 minutes ago and I went to the Microsoft site and downloaded everything that I thought would be required for Unity and these solved the problem
