hm, looking some more at this and the paper the algorithm is based on (http://wwwvis.informatik.uni-stuttgart.de/~roettger/data/Papers/TERRAIN.PDF), the implementation assumes that you have a heightmap of size 2^n+1 x 2^n+1. The paper indicates that is not a hard requirement of the algorithm, but it seems the implementation is based on this restriction. Can you try scaling your heightmap to e.g. 1025x1025 ?
