Hello there. I saw your post on AceHart's revenge of the skeletons. And I want to tell you that AceHart left TH some time ago. Why he left is a mystery.
What patch do you have ? Perhaps if you have 1.24 where Jass was messed up, that is why it won't recognise the map. I recommend either downgraiding your warcraft to a not crappy patch, or copy/pasting the 1.24 copy, uninstalling and then installing wc3 that you will update only to 1.23 .THat is the only way I can think of.
