SEP 11 Manager is not updating from Internet

Symantec SEP 11 Manager is not getting updates from the Internet. It can access akamai, and Liveupdate states that all the prducts are up to date, but it is not. The manager does show that there are new updates, but Liveupdate says all the products are up to date. I would like to know how this is possible.

You will get all the info on the picture.
