Look at the location of the element that is not converging.  Is it near a Fixed Boundary?  Changing the boundary condition or geometry may help convergence.

If you get 3 bisections in a row on the first substep, that suggests the applied load in step 1 is too large. Try breaking the model into a 2 step analysis.  In Step 1, make the load 1% of the final load.  Change the Initial and Maximum Timestep to 0.001 s and the Minimum Timestep to 0.00001 s.  These values may be extreme, but you must get the first substep to converge. If it easily converges, you can back off from these extreme values.

I assume you have Large Deflection turned on under the Analysis Settings.
