Which is why it would be better if macros are actually editable (i.e. having human readible text like instructions) - they could still be "compiled" in the background in their now binary format.
You can't resolve it, unfortunately. You will need to record the macro again. You could try suggesting to Helios that they add editable macros to TextPad. (It's been a frequently-requested feature for the past 17 years, so good luck with that.)
