I reloaded my 9900 after the error 102, all seen fine until I try to reinstall my apps, The uninstalled list on my world is empty, how one have any idea what to do. I can reinstall the free apps, but I certainly do not want to pay for apps or those gift apps again.
Reinstall. There should be no problems as long as you have not switched devices and have a new pin. Even then you can notify the developer of your new pin and then reinstall.
