Re: Need help with Storm 9530 Uncaught exception: java.lang.NoClassDefFoundError

Just found the cure!!!

Using the browser on my 9530, went to http://www.blackberry.com/appworld and downloaded the latest version of app world.  Didn't remove the old software and just said yes to download new verson.

Had to reboot after and when I went into app world it asked for email address and password and that was it!


Good luck to you all.  Hope you have all found this already!
