1) It can be any year in franchise
2)No I don't. They are attributes found in the game save for each player that aren't shown in the in-game player editor so I have no idea how the game uses them. Therefore, I just labeled them as unknown.
3)If a player is injured and can't play you could heal him in the editor. I am unsure if I would use this on my own game save because I know it is not fully hacked yet. I may remove it as an available option in the next release. (until I crack it completely).
4) You should be able to remove the photo.
5) You can edit player equipment/ratings at any time.
6) I believe most of the freezing resulted because very early versions of the editor being used, in which I used a faulty alogo. that has since been fixed. Also, moving players in the editor from 1 team to another was also the other likely candidate for the freeze problem. (This has since been removed).
Hope this helps out...
Cheers,
