Alright, this is my 7th time installing this new messenger. Every time i install it i get the same problem, All of my contacts are lost and when i add contacts they never show up no matter how many times i add them, When i import my contact list i still get nothing. Any idea how to fix this problem?

Picture below.

Press the layout button (the one next to Add contacts) and check if "Show offline contacts" option is active. If it isn't, that was the problem.

That box was already checked. It's not that i can't see my contacts, it's the fact that it says I don't have any at all. When i send people invitations they never recieve it.
