How is it possible you can't get Cybertech over 65? I'm level 39, and have it right around 360ish. Before you ask, I have Cybertech, Scavenging, and Slicing. I don't even need the metals from Underworld Trading to level it.
I'm going to guess he didn't train new schematics from the trainer since the purple patterns you get from reverse engineering the starting shematics gets you to 65 before turning grey (no crafting experience).
