If the error is what I think it is, then the same error should pop up for all John Wizard games. I know this as I had the same problem a little while back. I never figured out the specific cause nor can I remember the specific fix that worked for me to solve the problem. So, I can make a couple suggestions that come to mind. First, try redownloading the install and reinstalling the game. I don't think this option worked for me when I had the problem, but maybe it will work for you. Next, try restarting your computer. I believe this is what fixed it for me as it sounds like the right solution. Sorry that I can't remember, but I do hope one of these help
