So sorry to hear about the issues with Message+, HeidiMcCullough. I know how handy this feature is and I'm happy to help explain what is going on to clear up why you are having these confusing experiences. The Message+ Verizon Messages - Windows Desktop application is not compatible with Windows 10 computers. The Windows messaging client for Verizon messages is being temporarily removed to prevent syncing issues and customers are able to utilize the messaging web client as a windows alternative. http://spr.ly/6603ENVyJ The Message+ team is aware and working on a resolution.
