in need of help "Indicates two revision levels are incompatible "- UR12

Hi, I am in serious need of help.

So I got my UR12 soundcard. I did this several times and the only problem was wit digital signature, but I fixed it. Now I need help with this. I don´t know what could be wrong, but when I am setting my audio devices to my Steinberg USB it never showed there. When I get to Devices manager it is there but in this triangle with “!”, and when I click it it says: “Indicates two revision levels are incompatible”. I don’t get it which two revisions? Could anyone help me? I seriously don´t know.

My software is Windows 8.1, and the soundcard is UR12.
