Invalid client

Good evening once again I'm having trouble with the game opening, this time speaking to my client is an invalid version.
Someone from Z8Games need to solve this problem, it is not possible every time I have to play I have to uninstall the game from the download site and install again whenever you play ???
Meanwhile my days of the items bought with ZP go by and I'm not playing who will give me back those days? The mistake is not the end of my computer and yes you.
