Who I have the same questioned this topic

I'm using verizon message+ on my MacBook.  I had it setup with a previous phone number and it was working fine.  However, when I changed phone numbers and attempted to use the new phone number, after authenticating the code with the new phone, it stopped working.  It says "Database error occurred" and then closes.  

How can I get it working again?  

It seems like the database is saved, because it doesn't ask me to setup my phone again.  I can't get into the menu for it because it closes with that error immediately after starting it.  

I have already uninstalled and reinstalled the application several times.  Yet, the same issue keeps on happening.
