litchh, I tried running your map. The result is the same: in SoD, it gives an error, but it works in WoG. I don't know why, because in the SoD editor, it opens normally and no errors are found. Ask Talarasha - he seems to be an expert on map-related issues.
Another question: do you really need to rework other people's maps? Wouldn't it be better to create your own, from scratch? After all, if you're reworking them, it means you think you can do at least as good a job, if not better.
