How about putting in there some voltage source? And a ground wouldn´t hurt too.
I have no idea what that program is, but have you tried reading some manual, or some examples? Most software has this so I would be surprised if this didn´t.

Why dont you use LTSpice. It works, and has a GUI.

You need a value for the voltage source.

At least one node in your circuit must be connected to GND.

In components there is a part called voltage..
Use rigt click to edit parts.

no you don´t get it right click the part and instead of R write for example 100k

And the problem is? I can´t read your mind, so please explain it..

Go look at the example I posted. What do you see at the bottom?

That is the simulation directive. .OP solves the DC bias solution, and reports all the node voltages and branch currents. That is only one of several types of simulation that all Spice derivatives know how to do.

After making a schematic, Right mouse click any where in the background of the schematic. Edit Simulation Cmd. Select which type of simulation you want to do.

Sounds to me that you have not gone through the Tutorial.

You are doing a .TRAN (transient or voltages/currents vs time) simulation which is not really appropriate for a circuit where nothing is changing. For your circuit, do a .DC solution instead.

In the transient simulation you posted, you can see which node is node1, 2, and so on by moving the mouse pointer onto a blue wire. Note that it changes to a "Probe". Look down into the bottom left corner of the schematic. You will see the node number or name, and the voltage at that node.

For plotting, you can also name a node explicitly. Look at the sim I posted. Note that I labeled some nodes, such a B, E, and A. If a node is named by you, then it will have that name in the plot or the table that comes from the .DC solution.
