Too bad, it seems to me a problem with continuing a session.

Alternatives for cookies is offcourse a POST/GET variable. Since you're
using a form though, be sure you've configured PHP correctly to 'magically'
add the POST/GET variable so he user can continue his session and doesn't
start a new one over and over again.

What if you unset($_SESSION);session_destroy(); after a failure and then
let them retry?

Well, then that probably isn't the problem.
Could you enable some kind of logging, to check wether the users
experiencing problems can continue sessions?
