I downloaded it about a month ago, and it worked fine. The other day I played a game but it would not save so I quit and opened it again, but I got the regular screen but it was all black and when I clicked anything it turned into this:

Clicking anything again makes it not respond. I tried restarting my computer, redownloading the entire thing and trying other games but it will not work, and I can't get any other emulators to work :/
