@Maoh12 probably pirate?
Go buy the game you cheap scape.
They won’t support pirated games.
Go to C:\Windows and delete a folder called System32.
That folder is used by FiveReborn to store backup data but it causes problems sometimes. Restart your PC after that and try to open FiveReborn again.
If that doesn’t work, BUY THE GAME. Pirates will NOT be supported here.
