Darkilljoy, when you are logging in to your control panel it does not matter what your user group is on the site - it is a separate entity to your user account. As to your problem keep trying until it works. If the system informs you of using the wrong security code the best thing is to keep trying - refresh the page entirely and try again. If it displays the wrong password message check you are using the correct password (your webtop password) and that you don't have CAPS LOCK on.
