Kemper stage with kemper DI box?

  • Profiling my fender bassman - and running the volume about halfway up, to distort the sound. I'm running into the kemper DI box and into the kemper - when I start the profile it shuts down after a few seconds and says, my signal is distorting or overloading the signal to the kemper? I turned down the return on the first page all the way to -30 (i think its -30aprox) and it still does it?- I have to lower the amp to get it to profile but, that defeats the purpose. Any ideas help? i'm just starting to do the direct profile newbie thanks
