Yes i dont see my own banners on chrome but on IE i see them.
You might be logged using chrome but on IE you are not logged, have you check that ?
Caphacha is not default its adscapacha, and person who install it said i need to pm my template provider thats why i am here and bothering you =).
I see you captcha work well at FF using the same template, right ?
if it work with FF, it's seem not a template issue.
It's seem to be a captcha compatibility issue with some browser,
I'm sorry, we don't know much about this captcha, you should contact the one who install the captcha.
