Hello Dennis. I would recommend you to download and install the latest version of AutoHotkey. At the moment it is v1.1.15.
You can find it here:

This latest AH version is upgraded and compatible with Win 8.1:

I would also recommend you to use 76mm’s scripts. As he explained, my approach was completely different and, in whole fairness, not very good i.e. my method with X and Y coordinates comes with some shortcomings that 76mm successfully avoided. I am also using his approach/scripts myself and got used to "user experience" so much I can’t play PzC without it.
Regards
