Connected to my PC 3 days ago and I was asked to update the version of Kies and then the firmware. Unfortunately I did it before traveling. I completed the update and when finished, disconnected. It took for ever and most of my apps stopped working after that.. I had to reinstall most of my apps and still have some that don't work. It says "force to close". Obviously I called Samsung for support and they did not know anything about it. They are worthless!
Be careful, because unless I did something wrong, you may have the same problem!
