Cannot log into admin after WAMP install?

I am lost, I have installed CS Cart 3.01 on my local machine using WAMP. I can see the store front, but I cannot login to the backend. I put in the correct username and password, but it just reverts back to the login page, it does not even say incorrect login or password, it just does not go anywhere!

Is this a bug or am I missing something?

Much appreciated.
