Look here:

[vassalengine.org/wiki/Error\_Logs](http://www.vassalengine.org/wiki/Error_Logs)

In the same directory as the errorLog, you will find a prefs directory.  
In that, there will be a file with the same name as you module. That  
file will contain key-value pairs, one of which will have ‘maximumHeap’  
as its key. Edit the value there, and try loading the module.

I’d like to know what value you find there when you look. I’d try  
something like 512 to start with. (The value is in megabytes.)
