Since October, a subscription is required to read the magazine. So, the process is somewhat different. If you have entered some restrictions in IE for levelextreme.com, you may enter it as well for utmag.com. Try to clear also the cache just in case it would be related to that. Basically, after the login, you are prompted, if not subscribed, to purchase the subscription. So, that goes into https. So, if you have a proxy which doesn't allow that, that might also be an issue.
