That sounds like a problem with your .pmp file. I have encountered this, and it is caused by one of two things: #1: if you made the map using any mods, there is a chance that they might have terrains that are not in vanilla 0 A.D., which breaks the map, or, #2: your .pmp file is missing or named differently than your .xml file.

Are you missing a terrain? This causes a very hard crash.
