Part 1 downloads properly but when I open the folder and try to make the copy to properly play the game, that message pops up. I've also tried to play the game without copying the file from the "locked folder" it tells me there is a missing file or something. I'm not saying that you are wrong, its just that I cant seem to get the files to work even though I've tried a lot of times. I cant seem to play it on other sites without getting that rollback, ignore, open, or close screen. The part 2 download will not work for me at all and I know its not your fault either, cause I've tried downloading a different game and it said the same thing about decryption error or something as well. It might be mega is acting up
