... it is strongly recomended to follow CF SP storyline path withou trying to reach systems like X-3043 early. You easily can get stuck in systems (which are revealed by CF campaign) in moment when you advane in level and are started campaign scripts. You only can use your earlier save to get out of that system. I very recomend use latest mission save and continue from that moment.
p.s.: also do yourself a huge favout and never use autosaves, they are known as a source of various issues.
