First off, if this is the wrong place to request a solution to this sort of problem, I'm sorry. Anyway, I open the gui version of the pack utility and I try to unpack PMD Explorers of sky. One second or two later it displays a window saying that the .exe has stopped working and crashes. I try to use the console version of the pack tool and it gives me the same result. Am I doing something wrong?
