When you pass the function to execute the constructor of your buttons in menuprincipal you are executing those methods:

self.boton3 = Button(self.master, bg="Green", width=28,command=self.EXIT(), height=4, text="Exit").place(x=300, y=425)
                                                                        ^
                                                                        ^
                                                                        ^

This causes that as soon as the main menu is instantiated, the login window is launched ( command=self.Log() ).

You must pass only the name of the function, not execute it:

self.boton1 = Button(self.master,bg="Green",command=self.Log,width=28,height=4,text="Login").place(x=300,y=240)
self.boton2 = Button(self.master, bg="Green",command=self.Reg, width=28, height=4, text="Register").place(x=300, y=330)
self.boton3 = Button(self.master, bg="Green", width=28,command=self.EXIT, height=4, text="Exit").place(x=300, y=425)

On the other hand, the mainloop is only launched once. If you want to create secondary windows, use toplevel or redraw your main window (simply change the frame that should be displayed in the window in every moment). There can never be more than one main window in the same GUI and the entire GUI must run under that main-loop, and therefore, in the same thread.

There are more things you can improve, the names of your classes should start with capital letters. On the other hand, since you use classes you should create a class that is responsible for launching your GUI and avoid the use of global variables that should be avoided whenever possible. On the other hand, you open the text file but never close it properly, use with to open or close it after using it with .close() .
