Lost all settings menus text!

Win 7 64bit/1487 Portable
For a few days now noticed I’ve lost all text associated with menus. Can see all options but no associated text.
Rebooted and re-installed, tried Aero/non-Aero, sfc /scannow … ok, Event Viewer … ok
Unlikely a Listary fault, probable result of damage by other software or font ?
What language is Listary written in ?
Been setting up a lot of new software on Win7 machine so loathe to run a restore.
Any suggestions ?

Check all files in Languages folder, copy them from the original ListaryPortable.zip, and then restart Listary.

Thanks C that worked. Unzipped carelessly I think.
