No convergence of non linear problem

[jokiller70]

I get 4 errors calculating this model. Don´t understand why... 

Model to large to upload her, so here is a dropbox link to it;

What errors do you mean exactly?

I have set alll simple cases as auxiliary and then set full Newton-Raphson method with 0.001 without nonlinear and P-Delta check boxes marked to run the test calculations. I got the instability of type 3 warning which at this stage I ignored and all combinations converged with reasonable displacements and rotations in nodes.
