To recreate steps:
-Launch Dayz.exe
-Wait for load
-Home screen loads in [starts with polygons, etc. and details are added in regards to graphics settings]
From here onwards, 2 possibilities:
-Here on, clicking Play freezes the game.
-Additionally, if change server sis selected, the server list remains unpopulated. Clicking refresh, adjusting filters in general, or selecting any other tab produces the same game freeze as play.
