After completing the objective for the Means to an End quest. I am prompt to talk to the drifter. I talk to the drifter then he tells me to access the Prismatic Reactor. When I go to interact with the reactor, the dialogue displays with the enter button to continue. I hit the enter button on my computer and it opens the chat box. I even tried clicking on the box to see if that would work but nothing. I am stuck and can make no further prohressipn.
