Message+ is gone. A generic message appreciate is showing

Verizon Messages+ has been going through some growing pains the past couple of days.  It's currently on version 6.4.3 with another scheduled to roll out soon.  I advise using the stock message app that came on your phone for now; wait till this all sorts out before trying to use Messages+.  It's a mess right now.
