I went on there and I signed up, cause you have too. Everytime I go to see something (once im signed on) It asks me to sign in again. It just keeps going on like that, you might want to check that. Just letting you know.
If your being taken back to the login screen each time it means you browser is having problems creating the HTTPS session used for security. Try to clean out your cookies, temp internet files etc and see if that helps. Also if you are viewing the site through AOL, try viewing it directly through IE or FIREFOX and see if that helps. Hopefully this will help you, if you still cant get it to work, dont hesitate to call the shop with your questions/orders.
