Okay so I have the newest version of Java installed the one suggested to be able to use the flying mode. Every time I try to open the file titled mincraft.jar an error noise sounds and nothing happens. I have tried to open it several times still with no luck. I even re-downloaded the file still with the same results. Can anyone please tell me what might be my problem and if they cannot help maybe tell me how to contact someone who can?

Thanks, Seancage
