libMesh: A C++ Finite Element Library

Hi, 
I am trying to modify the code in Miscellaneous ex 7 to solve the cahn hilliard problem with c0 elements, and I don't seem to be having any luck getting it to work, the solver only does one residual computation and moves on to the next time step. Has anybody seen a similar issue with this? It also shows no reduction in the residual. It is the same matrix as the one solved in the petsc example 54, in the petsc snes examples. 

THanks,
Subramanya
