This is an older version of elements, and as you have realized it will not be able to communicate with Photoshop.com . You can use Elements without Photoshop.com, you just will not be able to sync to our online cloud.
Did you try to enable a sync or interface with Photoshop.com? This forum is for Revel, so I am not very familiar with the settings in the old Elements program. If there is a place to enable this communication or login, you should disable it. I will try to find an old copy of this software and load it to see if I can help further.
