The Black Chancery Font is not installed by Windows or Word, but could have been installed by another 'program' such as Corel Draw.
Uninstalling that program will not uninstall the font ... so I'm a little lost as to "where it went" ... your best bet is to find another 'copy', either off the Internet or from your programs.
To install any fonts you may download ...
Go to c:\windows\fonts and select FILE, INSTALL NEW FONT, and in the ADD Fonts dialog box, select which drive, folder, the new font/s are in ... then after it has listed all the fonts available, you just highlight any of the fonts you wish installed and follow the prompts.
I hope that was of some help.
