I have tried it and just get a constant 13V. I am not sure what you mean by "it was node 4 at the 2nd line instead of 2" - line 2 is Vee 0 B 15V (or Vcc A 0 15V if you count the comment line). No 4 or 2.

I don't know what you are connecting and how but X1 and X2 have their outputs shorted together which isn't good (node 3).

There are demo versions of Pspice around (and other simulators - I ran this in SIMetrix). You would be better off using something like that and drawing a schematic.
