So for the first month after my GSX purchase, everything went without a hitch. I rarely ran into problems, in which an error message would pop up telling me that the Couatl engine was not responding (this happens rarely, usually in modded airports). I would just restart GSX through its menu, and it went back to normal. Other than that, I had no problems... until today. So when I fired up FSX for another usual flight, I noticed that the GSX Menu would not appear. I clicked Shift+O (the key I've linked to open up the menu), and nothing happened. Not only that but on the bar on top of the screen (after pressing ALT), the Couatl menu had disappeared without a trace. I have no clue what's causing this. The only abnormal thing I did was download Java (this was so I can install another, unrelated addon). I'm not sure what else would be causing the problem, as I downloaded Java the day before, but I did not check to see how it effected other addons I had.
