New CLient

After a game i played yesterday, the new client automatically shut itself down for no apparent reason. Then once I start the client back up again it gives me an error saying the whole game data was corrupted. so uninstalled and reinstalled it. Put me back to the old client and cant even play update it since theres no way for me to play or even install this shit. Been playing for over 4 years now and all of sudden this shit happened. When exactly is the REAL DATE when the alpha client is available to everybody. THis shit is starting to piss me off.
