Registration fields – none being accepted

I’ve just installed this plugin, but when I try to register a new affiliate account, none of the registration fields are accepted?

This is what I get:

Register

First Name * is required
Last Name * is required
Phone Number * must be a valid phone number
E-Mail Address * must be a valid e-mail address
Address Line 1 * is required
City * is required
State * must be selected
Zip Code * must be a valid zip code
Country * is required

I’ve double-checked the information I’m putting in, so I know it’s correct. It just doesn’t accept anything?
