Emotional Dot-Probe Task HELP

Hello, 

We need to use a dot-probe task in our experiment and we are having some difficulties to do it on e-prime. We have downloaded this version to use as a model https://support.pstnet.com/hc/en-us/articles/360046510573-Dot-Probe-Task-34333- however it was not fully helpful. 

Our task will have emotional faces: neutral, angry, sad and happy. The hardest part is being with the script to run the response data, since it is not accurate. Does anyone have a sample to give it to us so we can use or some assistance in this case? 

Thank you very much in advance.
