I'm having trouble getting into a room and being able to see the chat room on my screen? What's up? - pop up screen room

In the last two days I have tried to give a couple of cats. "I still have my messenger screen and I can see, but I see the chat message area. Needless to say, I'm in the room, but I can not see. I have no idea what he's doing. I uninstalled the system repeatedly re-installed and working, the hope of solving the problem, but not. Can anyone help?
