heyy i can't open the game because it's said that it can't read textures/mega.data
That’s a new one on me, make sure you didn’t take that out of there or modify it. You might have to get a fresh dl. You’re saved game should still be there.
I have another guy with this problem on Windows11. There may be an issue, I’m looking into it.
File permissions? See the note at the top.
