You can try adding #USEOLDENGINGE#=TRUE on top of the script (for example below the line #SCRIPTGENERATION#).
Otherwise you can simply add the new substitutions necessary above the #ENDSUBSTITUTETAGS# line.
Example
#SUBSTITUTEWORD#=<as shown in XMM8>=<as shown on website(htmlsourcecode)>
#SUBSTITUTEWORD#=A¨, ...=á
I don't know if my example is true!
