Skype isn't working

So a couple of days ago I noticed that Skype on my PC was acting weird. When I tried to open it, it wouldn't open. So then I turned my PC off and on and Skype still wasn't working. So then I tried to access it via the desktop short-cut and it opened, but it looked like 2 Skype windows were open at the same time, I then tried to close the first one but it wouldn't go away. Then I tried to sign in and it said that I was already signed in.
