I am experiencing a peculiar issue where I can't see new messages that got sent to me nor messages that I sent to someone else. I am running Windows 8.1 and Skype 7.1.0.15.
I can see some old messages, when I scroll down and send (or receive) new message scrollbar jumps up. I have tried restarting Skype without luck.

Figured it out myself.
Quit Skype and delete C:\Users\[Username]\AppData\Roaming\Skype then start Skype and you should be solid.
