Hi all hope you can help. Tearing my hair out. Bought a behringer uphoria UM2 as my first audio interface. Plugged it into my windows pc and and a driver called usb audio codec appears. Sound from the pc is going into it fine. I set up the free version of Guitar Rig 5 as the amp sim but when i plug my guitar into the interface, nothing happens. When I look at the inputs in the audio section of Guitar Rig they are all showing as NOT CONNECTED. Spend a while online looking for troubleshooting guides but cant find a thing. Any advice welcome. Have I done something stupid? The installation instructions that came with the interface mentioned the need to download the latest usb driver but when I went to the website it was sending me to an external link. Also a behringer quickstart video on youtube says that there is no need to download anything. It should just plug and play
