EMPro simulation gives always an Error. (ADS, 3D momentum simulation extension)

HI, recently i started simulating a very simple wave guide structure on EMPro, a 3D Electromagnetic simulation environment included in some ADS extensions. I followed some tutorials online several times and everything works perfectly except for the simulation, which at the starting phase gives an error and it doesn't continue. The log of the simulator is pasted bellow.

I am running EMPro locally and performing a very simple FEM simulation following the steps of the tutorial that I've attached to this message. I also included some of the very simple test projects that I was trying to run without success, just in case that maybe someone can run it and tell me why it isn't working as I expect.

However, I am looking for other software possibilities just in case that this one doesn't work eventually. I know HFSS, but I wanted to start with something simpler like EMPro to perform some basic test on some different waveguide topologies. Any suggestions?

Thanks very much in advance.

It's working in Empro 2017.U4
