Thanks Alexandre for the solution but, could you please provide a more detailed explanation of what exactly needs to be edited in the file?

You mention 'simply commenting out lines 376 to 386' but when I open the file in Notepad, It's just one big paragraph, as well as the fact that "commenting out" sounds like programmer's jargon and so I don't know what to do.

Please describe exactly what text needs to be replaced, before and after.

Even better, could you make the fixed file available for anyone to download?

Thanks and regards,
Mal
