Let me know if it works for you as well.
Next time you run into this problem you can load the map in the latest ScmDraft, then go to File > Save As > here set Save as type to:
Raw Starcraft: Remastered Broodwar Map (*.chk)
Or you could use Ladik’s MPQ Editor to extract the .chk:

Then open the saved .chk file again in ScmDraft, then go again to File > Save As > here set Save as type to:
Starcraft: Remastered Broodwar Map (*.scx)
Now the map should work in SC:R.
