I use Line. Not sure why? It's very slow loading. I much prefer Messenger. te2008, try uninstalling, but make sure you know your user name and password. It can be a real pain if you forget these. Not sure why your contacts cant receive but they can contact you? Go into settings and check your privacy settings and notifaction settings. Check your account settings too. Right at the bottom of settings is a help icon, not sure if that will sort your problem out. If not, get on Messenger Good luck.
