Systats font keeps reseting.

I downloaded this systats thing, http://hyral.deviantart.com/art/mini-Digital-Clock-12347215, and I modded it.

I just basicly changed the font. Whenever I restart Avedesk, it reverts back to Microsoft Sans Serif..

What can I do?

[Edit] This is also happening on some other systats things, is it a problem with the font?
