If your dsl is disconnected then how do you expect to recieve updates from SDC? SDC needs to connect to the internet to retrive the updates. Also, How is it that your DSL is not always connected? DSL's are supposed to be ( Ithought) an always on service. If you try to retrieve updates when you are connected and you can't, and you're still getting those error messages,I suggest you try uninstalling and re-installing SDC.
