Glitch prevents me from using scenario editor

[ElectricSquid7 33]

I've recently downloaded two scenarios from my friend, Boblik, that he shared to me personally. After downloading them, I found that when I tried to open the window that had a list of all your scenarios, it took me to the main menu. This was an annoyance, but not detrimental to the gameplay, so I thought little of it. However, I soon found that this same instance occurred when I tried to open the scenario editor, rendering me unable to access it. Can somebody please help me out here?
