Yes, two accounts on the same machine, one with no problems at all and the other unloadable.Wow, both accounts in the same machine? in my case was more simple, the Orange error only happened when I was trying to land on any planet in Odyssey, I had to restart with the vanilla ED game that places the ship again in the space. After that, I rolled back to the adrenaline previous driver (the problem began after update the Radeon driver) and everything worked ok again. But your problem is by far more complex if both accounts are in the same PC.
Frontier has now come back with some ideas. She moved me to one of my other docked ships in another system, and even though the load time was long, I was actually able to get back into the game with this ship. She then moved me and the original ship to a station in Colonia, which I was one (neutron boosted) hop from. When trying to load the game again, it still gives the orange error. She concludes that it must likely be a problem with the ship itself, and I am waiting on a solution for this.
