I have a problem with the SteamVR plugin. I created a new project, imported the latest SteamVR plugin (2.7.2 sdk 1.14.15)
When running unity, I don't see the controllers in the 'Game' window and they don't work (none of the commands/buttons are working). The only hint I have that there is a problem is the message I get (SteamVR Interface Not Found (105)) I tried to look for a solution on the net, but couldn't find any solution. Please help/advise.

using Windows10
Unity version 2018.4.20
