Hello. I have a problem with game maker. I can't understand it. The game just crash when I press a button. But I don't know why and it doesn't show any error message. I tried to remove the code step by step in the button and look like the error is "file = get_open_filename("Text file|*.txt;","").
But I used that code before and that worked. And some buttons that worked before don't work anymore. WTF?
