Inferno – “A fitting image for you” [Campaign 5, Mission 2]

Something tells me that it's better to play the campaign with Conflux enabled... Do you have a licensed copy of the game? If not, anything could happen with a pirated copy. If it's a licensed copy, try playing with Conflux enabled so that your progress is saved and doesn't get reset.

However, it's unclear how you're using Dynasty weapons without Conflux. It seems that we're actually talking about a cracked pirated copy... Unfortunately.
