I downloaded 5.1 just now, and when update was finished, restarted laptop. clicked Skype icon to connect, and the old log on screen with my old password came up and idled for ever without connecting. How do I get rid of the old "log me on" box with the old information?
Quit Skype or use Windows Task Manager to kill any Skype.exe process. Go to Windows Start and in the Search/Run box type %appdata%, press Enter or click the OK button. The Windows File Explorer will pop up. There locate a folder named “Skype”. Rename this folder to something different, e.g. Skype_old. Restart Skype.
N.B. If needed, you will still be able to re-establish your call and chat history. All data is still saved in the Skype_old folder.
