what version are you using? i had problems using 1.1.0. reverted to using 1.0.0 and never had a problem ever since.
I have the same problem. I used SwitchMon a year or so ago when I played for a bit again, but I guess a Windows update broke it since. I uninstalled 1.1.0, and now no other version will load. I can see them pop up in task manager, but that's about it. Run as admin and compatibility are useless. Frustrating.
