OK. I have figured it out. My issue was that I could not find the Zorro.mq4 file. My bad. I must have searched for the wrong file name, as I could not find it previously.

Might I suggest that the manual remarks be updated to reflect "For this edit the assetFix function in the Zorro.mq4 EA located in the source folder" or something to this effect, just to cater for some slower members of the team such as myself.

Thanks for your help Ddlv.
