nikost

I have a problem with WLM 09. As it says above, all of sudden the default icons do not appear in the chat dialog! I can see them in the menu, but when i type them they are shown like this " : ) "

I haven't made any changes, this just happened in a moment. Plus the " i'm " logo has disappeared too. Now i can see my nickname as "*9mil nikos"

Does anyone know how to solve this?

thanks!
