Embedding font works, not at the glow filter doesn't!

This is the link of my project. I embedded a kind of pixlated customfont say “font.tff”. As you can see the clock in the right corner uses this font, but the glow behind it, doesn’t (on my other computer it is).
How do I fix this? I already manually embedded the characters at the dynamic textfield.

If you hover over the “city” in middle left, you’ll see a stats window. The font there works fine.

Can’t really find it how i fix it… Help is much appreciated!
