Can't load map in Zephirs editor?

Well we are in the home stretch here in my map's development. Al lI really need to do is paint pathing (i used funky elevations) but I cant open my map in Zephirs editor! I'm using 1.05 WE + 3.6 UMSMAPS + 0.8 Zephirs Editor. Here is the error I get:

Hmm... If you used any special tools like doodad enlargers or the limitless terrain height tool, that will cause this error. But this thing is old, and pokey at that. So it might be best to do whatever you wanna do first, then use the WE.
