Re: Pc properties
If it was blank before (icon) and you had to manually choose how to open it, then just asking the PC to open it with notepad shouldn't actually break the game that you're trying to open, you've changed the file associations, not the name of the file. Of course, if you then saved the file as a .txt file, then the game wouldn't work, but I'm guessing you exited the file without saving.
Can you tell us any context please?
