Feral Heart

So I made a new Roleplay that I am really proud of, so I want to advertise it. I go onto Feral Heart and I start to make a movie. But before I can publish the movie, FH crashes. This has happened before, but not this early, so I go back and log on again and try to make another movie. The same thing happens! My FH usually only crashes when I go on as one character, then leave and edit that character or switch charcters and go back on. Does anyone know why it crashes?
