So, I preordered OW standard edition (40€) and it says that it will be available at the 24th of may. And it also says in my battle.net account that I have bought this product.

Played 2-3 games starting at around 20:45CEST and then the game stopped the auto-search for games. Then tried to relaunch the game and couldn't connect to the server.

So I guess it's over now ? Will have to wait until 24th of may to play it again ? :/
