Captcha images are not working

[MLeeper]

It appears that all of my Captcha images on my site are not working. Any thoughts?

What script are you running and what is the url?

There are two separate "scripts", both were working until today. :dunno: The main Captcha image uses phpCaptcha class. The other is a plugin for Community Builder for Joomla for site registration. Everything but the image works. My site is http://mlwebtechnologies.x10hosting.com . Please advise. Thanks!
