By myself. I have tested version 1.2 and 1.3, both have done the same problem. They load the map until like 10% is left on the bar, and then it just quit warcraft. I have got version 1.22.0.6328 of warcraft, and I am playing it on an intel mac. It may just be something with my computer, though it's strange. I can't open them with the editor either, though I guess it's because they are protected. Still with version 1.3, it gives me a "unit data missing or invalid" error.
I hope this will allow you to fix the bug.
