Problem with captchas and password strength in WHMCS Integrator

Hello,

I have Wordpress setup with the plugin at http://maret.euronetagency.com/portal

It seems to be working fine except on the new user page for WHMCS within Wordpress. I can't get the captchas or the password strength images to generate.

Thanks!

EDIT: I managed to get captcha working by installing GD2 library on whmcs server (doh..) but now I just need a solution for the password strength bar!
