[SW217]

I had problems with this update myself over the weekend. I talked with the Sprint advanced technical support (initially called 877-345-7895 was then transferred) and they advised that it was possible the upgrade did not remove the original .exe file. I did a hard reset, 3rd one in 3 months. They sent a link to http://otacdn.telenav.com/resources/...PPC_5.5.18.cab (I typed this so hopefully no errors) he was very clear to tell me to save it first and then to open it to run the file. The app then opened. It did ask for a password, which was news to me. I entered the last four digits of my phone number and it worked.
