Hmm. I'm not aware of that error personally so don't know what to suggest. Did you run it as admin?Okay, I converted my save file to a DB file, opened it with DB Master, added Nasri record from original DB file. But I can't save in DB Master because I got "cannot convert DBNulls" exception. A tried to save the DB file I opened (without any changes) but the result is the same.
I have another idea. If there is a player in the game with unique (real) face, can I replace his face? So I create a new player and I want to set that he has Nasri's face. Is it possible? Maybe with Cheat Engine, for example.
I think the DBM method is the only option.
I'm only repeating what I've read but Cheat Engine won't work. Unique faces are tied to players' IDs and changing the ID in CE is not adequate because although the players' appearance will change, the players' statistics will be recorded according to his original ID, therefore crashing the game.
I haven't tried myself though - only repeating what I've read - so you can try.
