I am doing a Simulation with a hyperelastig material and an indenter applying pressure on it. Recently I keep getting this error message using the Direct Sparse Solver:

Exception code 0xc0000005 thrown at address 0x941260df in: Nstar.dll file version 29,3,0,7.

Using FFEPlus or LargeProblem Direct Sparse works. The weird part is, direct sparse used to work but now it does not anymore. I tried repairing SolidWorks, but the error persists. Any ideas?
