Glitch in Time Travel Challenge

I reached the point in the time travel challenge where you are researching something on the computer and the computer is supposed to get broken by the research. The next task in the challenge is "repair the computer" however, when I was doing the research challenge task, the computer never broke. Since the computer is not broken, there is no way to repair it. So, I'm stuck on this step of the challenge because I cannot repair my computer.
