[Help] I can not install a new card

[Eclips]

I want to make my own maps with Loren Market card I want to replace it with Lorencia replacement, but the game client gives me an error (Date error) and if I put this card as a mix of the standard Loren Market, then everything works fine.
Tell me what could be the problem?
