Trouble restarting

Hi,

I am working on a shear cell simulation. I run the simulation in different steps (filling, cleaning, shearing...). The problem is that after I finish the shearing operation, I noticed that I have not attained steady state for the shear force. I want to restart (this is the 3rd restart that this model will see). The model will not restart from this point. I have included all the files needed to (try to) run my model. I get the following error:

Setting up run ...
Import and parallelization of mesh base containing 552 triangle(s) successful
Import and parallelization of mesh base_sides containing 384 triangle(s) successful
