When I restart my smartphone the next sync with my Windows 7 PC over WLAN will fail. The message is "Unable to connect to DejaOffice. Verify your IP address in CompanionLink."

I must launch DO separately to have a sync success. But I've the today-DO-widget on the homescreen - so for me it's started

Which setting do I need to make DO sync-ready with every (re-)start of my device?
