The error message says bad CPU type. Any tips?

If I had to guess, you probably have wrong settings in the Arduino Tools menu. (Might as well share that along with the error message).  
The full error message would help probably though. I don’t personally mess enough with Arduino to know off the top of my head.

Ah, that seems likely. I had forgotten about that.
