Map Editor Keeps Crashing

[Ephraim]

I've been using the Map Editor in Tiberian Dawn to build maps.  I usually work on a map for a while, save it, and then close it.  However, when I come back and reopen the program and load the map I was working on later, the program will always crash.  I can never finish a map because of this.  The error says "The program ccwmap.exe has encountered a serious problem and needs to close.  We are sorry for the inconvenience."  On the bottom it says "windebug_what_happened_message."  Any ideas how I can solve this problem so that I can finish a map?

 

Lastly, when I open an unfinished map, the terrain always reverts back to temperate.  Even if I build a desert map, when I open it back up it will appear as a temperate map before it crashes.

As wild guess. Try loading the terrain via New or how you make a new map than try load the map.
