Hi,

I'm working on an example that is provided on Proteus simulation examples.

I opened a file that contains a circuit that has 2 AC sources, which I don't know why they used 2 AC sources, so I deleted one and started to get the results I want.

But another problem that I got is that if I add a ground to the circuit, then a fatal simulation error occurs.

This is the circuit:

Also, can anyone explains to me the directions of the current, is it the conventional or the real current direction ?

I learned that the conventional is the protons direction and the real one is the electrons which flows in the opposite direction.
 

As the pop-up windows says "see log error" one would expect you have attached/paste the error message. In any case, it is likely to be a problem related to the use of 'ideal' devices (for example, diodes, capacitors) that not rarely can result in convergence errors. Try to add a high ohm resistor - 10 Meg for example - between the negative terminal of the AC power supply and the grounding node.
