[A19e Nitrogen - UNSTABLE]

I have Java x64 installed. Getting this when generating map. Any ideas on the problem and how I may fix it?

 

creating output directory: Walkabout  C:\Program Files\Nitrogen Map Gen\NitroGen_WorldGenerator\output\Walkabout
output directory created
... running terrain generation ...
