Captcha - not all letters showing?

[nickelas]

The captcha has stopped working for me. The black letters are showing but it seems some other letters are missing. Easy to see on the register or contact-page.
It used to work fine, so could it be connected to the 1.5.18 release?

Thanks,

Replace images/fonts/acidic.ttf with a fresh copy from the official Coppermine package, as that file is corrupted on your server.

Terrific, thanks
