You did read, undend follow the instructions from Adafruit?
I did and everything seems to be installed correctly. I can get it to load, communicate and serial monitor just fine, but its spits out the error when compiling this specific code.
The TrinketHIDCombo library is written for use with the Adafruit Gemma or Trinket. Although the Trinket M0 has a similar name to the Trinket, it is a very different board and is not compatible with that library.

Cool - but it's not an Arduino issue! This is NOT the Adafruit support forum!
Arduino is also a Integrated Development Environment made by the Arduino company. That software is supported here. The OP seems to be having a problem using the programming environment, namely Arduino.
OP,she's right though. There is also an Adafruit support forum, Unlike this forum, questions there are answered quickly by employees of the sponsoring company. Opinions and conversation is kept to a minimum there, which is both good and bad.
