No text in XBMC

I jailbroke a ATV2 for a friend and it worked fine on my Tv but when I sent it to him he says that in XBMC there is no text showing up (i.e. VIDEO, PROGRAMS, SYSTEM, etc. do no show up on main screen) He does have icons but no text underneath those either.

If I could get some ideas of how to have him correct this it would be great.

I’ve seen this happen when people change the font or the skin

Make sure that the skin you are using is compatible with the version of Kodi that you are using.
You can often find the latest version of your skin by a Google search which will lead you to the download page for the latest version.
