There is no new HUD in all servers.
wZH was made with new HUD so i guess it doesnt work with old HUD
Try out 5.13 version for old HUD
If it doesnt run
If it doesnt run. Try to turn off Windows SmartScreen
As for me, when i downloaded .zip and run .exe i got this window (win8+ I have win10):
Just click the underlined word and:
"Run anyways" button or smth like that
