I installed Windows 10 and now my Verizon games do not work. It looks like Gplayer has disappeared.
Windows 10 automatically uninstalls applications if they're not compatible before starting the upgrade. This is the reason why Gplayer is missing from your computer. Technically, you should download it again, but if it hasn't been updated for latest version, you will encounter issues with the playback or functionality.
You can check the official website for more info, or use the Contact Support button to get in touch with the developers: http://games.verizon.com/do/index;jsessionid=B9B8065F2BD864F17835C3367B20287F
