REALLY Quick help to embed a library in EA (both are ready)

I need some help to embed a library into an EA. Really quick stuff

This is the library and instructions: https://www.mql5.com/en/market/product/23068

I was able to add the header file and the codes. The EA runs the optimization, I can see the results in MT5 strategy tester, but the output files (generated by the library) are blank. I'm almost sure it's because I'm doing something wrong when adding the header or the required codes to embed the library. 

It should be really really quick. 

thanks.
