Kik (Problem) Help please!?

[Pepito]

When I send messages on Kik '...' appeared next to the message. I waited like half an hour and it was still the same! I re-setted Kik and when I came back on there was a red exclamation mark next to the messages. I clicked on it and sent the message again but the three dotted lines (...) came up again :/ My internet connection is good so I don't know why this is happening! Should I delete Kik off my phone and re-install it or something? Thanks
