Installer Problem

So i downloaded Gamezbd launcher and after installation every time i open it an error message will pop out " Invalid Namespace" and i thought i have an old Gamezbd launcher and notice that the old launcher size is 19mb while the new one that i downloaded is only at 9mb and i installed the 19mb one and it works but the problem of that installer is it's looking for a Black Desert folder with all the game files which i don't have and if i close that window it will not download the game at all.

IF you look on the date on the 19mb one it's last year while the numbered ones i just downloaded recently.

 

Try this one: Click to download

 

I downloaded the mirrors on guide forum and then download another gamezbd installer then replace the exe to the exe posted here and still the same Invalid Namespace Terminating Application.

It's a shame because i dl 30gb of files and its not working

Edit: Installed the 19mb one (old installer) and the window pop up for the path of black desert but after that the launcher updated (reach 100%) and then the error pop out again Invalid Namespace
