VR not working with older projects

Hello,

I had an older project working absolutely fine after packageing, booted into VR no problems. Since then, i’ve had to update my PC to Windows 10, and i have the oculus home firmware, and now nothing i do will get the old project to boot into VR mode. ive tried all the commands but nothing works, the absolute worst part is that i tried to update the project and export it again in a newer ue4, but now it fail packaging every time!

Please Help!!
