Code not displaying on gift certificate

I've set up a gift certificate sale for today -- the 19th I've done with no issues -- and the preview of the certificate is not displaying the code properly. If I look very closely, I can see a very faint image of the code. I did a test purchase and the e-mailed certificate was the same way. Also, it is displaying a second line of text with a dollar value that I did not designate.

Please help -- the sale is set to launch very shortly.

By the way, I tried setting one of the previous certificate profile, one that I know worked properly, and the image is the same.
Thanks

it sounds like you may have an error of some sort in the background? Can you look at your error logs? If you want me to look at it please pm me temp admin/ftp access.
