The Oracle Java update for Lion just isnt recognizing it! I have mac os x lion 10.7.5 on my laptop and for some reason, certain Pogo games wont load..it says its loading but never does and just closes. I went to the help page, did what it said, I scanned for current updates, installed them, rebooted then went back to Pogo and clicked on the java test link to see what version im running. I got the error 'missing plug in' so I clicked on it and was taken to Java's website for instructions, clicked 'Download Java for Mac OS X,' then hit sytem requirements and saw that I had to be running os x 10.7.3 or above and I have 10.7.5. I was good to go, hit download and now Im here! Annoyed and confused beause updates and upgrades are pretty basic and simple. You either meet the system requirements or you dont. I meet them but cant get them cause it says I dont..its a viscious cycle and Im rambling like a madwoman! Is there an easy yes or no answer to this, maybe a follow steps 1,2,3 A,B,C you can post for non computer savvy moms? LOL I just want the handful of Pogo games I used to be able to play, to play again..nothing complicated! And why is it only some games and not all of them? Dont answer that, my hair already hurts..haha
