Change Reputation

[Ashar]

During one game a trader told me about going to XB-13 and at a station there i could pay moeny to alter my reputation with the various factions, however, i recently restarted my game, but never got this message. I tried going to the system, but the npc at the station doesnt give me anything. Is there anywhere i need to go first? i cant rememebr where i was when the trader sold me the info
