Game was running fine for about 3 weeks. Went into the nether with 2 other players, my unit was server. Came under heavy attack and was throwing snowballs. Ran out of snowballs and tried to access invetory for more. Was killed in the process. When I respawned The afore mentioned proplems arose. Have dumped the entire system and redone as per PS directions ,no help. Inserted other games to check system and controler, they work as they are supposed to. Retried minecraft and still no results.
