Error running bot

I am trying to run a script on Autoit except I always get an Error

#include "gwAPI\constants.au3"

Could anyone shed some light on what this means and how i can fix it.

The script you are trying to start, wants to include the fiel "gwAPI/constants.au3"

Be sure following statements are true:

#1 In the same directory of you script should be a folder: "gwAPI" (case sensitive)
#2 In the folder "gwAPI" there should be a file "constants.au3"
