hi, i just installed this module, but i found a problem at the check-out page. i wonder if this occurs to anyone else. Any response would be appreciated:

At the check-out, it does not have a credit card type option for customer to choose from, e.g. Master Card/Visa. please see the image:

I've checked the .php and the codes are there.
