Sorry, in that case forget it.
Most probably there was something wrong with my pc. Between the time in which the Dom Kavash gave me the coordinates and the time of the failed mission error passed no more of 10 seconds for sure, and I thought that I have to wait the comunication between me and the Dom for story purposes.
@Martind: never tried to fight 3 savage cruisers, I was trusting around like a butterfly waiting for the Dom to save me
As always thanks for the mod and the reply. Only another question, in case I want to spend the money piling up is possible to finish the single player with a cruiser or I will need to dock with station that allowed only fighter?
