[Q] Why is my client not up to date?

Hey just wondering why my client is not up to date when I add my last weeks share to my newly unpacked and CRC everything is fine it's just when I put last weeks share file in my new one and launch it give me an error when I try to go in. It says "Your client is not up to date".

maybe the some new items in the last patch ?! Oo

need me new share for 25 m in siz XD

probably cause of monster.csv -> Christmas Nightmare or however its called
and itemetc.csv -> if any of the event items are not d-shop items
