    it sounds like a fualty installation of Lion, this may happen from time to time.

     

    The best thing to do in this situation is to reinstall Lion. You will not loose anything doing this, but you should always keep back ups of your information.

    basically hold Cmd+R on boot..

     

    first go to disk utility, verify and repair your disks and permissions. Exit out of Disk utility and then go directly to "reinstall Lion"

     

    choose that and let it reinstall.

     

    Adobe CS6 does need Java to run.

     

    To play your movies you might need to get an application called VLC. VLC is a free app and will play most videos and music files you throw into it.

    you have a 64bit intel mac, so get the one for that.
