login

Question

I made a Register and Login Form.  It is working,  but when logging in it is not doing a good job.  Sometimes it logs out even after a few seconds.
you can try it at:
www.christens.be/register.aspx
www.christens.be/login.aspx
Did I forget something?
Here the code of 2 web.config's, first web.config in the root then web. config in the directory:

<?xml version="1.0"?>
