I can not get the Verizon messenger desktop app to work on my laptop. I can get it to work on my cell phone just fine but the desktop app will not except the security code when I enter it. I've tried it over a half dozen times it it keeps telling me to enter a valid security code. It worked like a charm when I downloaded the iPhone app onto my via and put the security code in that was generated for that. Didn't have any issues whatsoever for that one. My laptop is a MacBook Pro and I downloaded the app from the app store. Any ideas?
