If your cookies are already enabled for your web browser and you have received a message, stating they are not.

There are several possibilities for this problem.

1. You may be running software (security/firewall/anti-virus) that interferes with cookie usage. There are many filtering and blocking software out there that will block or unintentionally disrupt the usage of cookies. Please make sure you have cookies enabled in your software, or add the appropiate domain to your "safe list" of sites.
2. Your machine may be behind a firewall or proxy server that prevents cookie transmission. This is most likely in a corporate environment. So, regardless of how your browser is set, cookies won't be sent or received by your browser. You may want to contact you System Administrator about this issue.
