Flex doesn't work

I’ve been using Nvidia Flex for about 2 months and everything was great. 2 days ago I updated my win10 and now i get this: https://www.youtube.com/watch?v=T6lnR9N8A0g

I’ve reinstalled flex, rebuilded it, even reinstalled VS2013… Nothing worked. Plese help, I’ve been trying to fix it for a week. Really don’t know what to do :(

Can you check in the nvidia control panel to make sure that PhysX is not set to run on CPU? If the update has bumped it to CPU simulation, this could explain the issue you’re seeing. You should ensure its either on auto-select or set to use a specific GPU if you want to use GPU-accelerated PhysX features like FLEX.
