Visibility of Nodes

Hello,

I´ve been trying for a while now to be able to see nodes in the main screen (WITH DEFAULT PREFERENCES), in the new version of Hyper mesh 2019 Student Edition,

I just enter the program, clicking the Optistruct Solver, but when I try to create a simple node or multiple, they don´t simply appear in the screen (not even by fitting the screen)

On the other hand, when I create a line, it becomes visible as normal, but nodes still are not.

Is there any visibility option I might have disabled by default? 

Thanks!
