Stretching silicone rubber

I am trying to run a simulation on some elastomers that we are inflating with air.

 

 

I am running a Nonlinear Study with 2D simplification, and I want to see the stresses at specific points along the geometry, but after reaching about 30% of the solution, I get the classic error:

Looking around the web it seems like using Arc Length control method should help me over the buckling stages, but it still seems to fail, in fact even sooner at about 25%. I am not sure where to go from here, and there seem to be scant resources on how the Arc Length method actually works and what each of the settings mean. Any suggestions?
