If you run the dbsUpdater program manually (its in the game lobby folder) it should connect in to the new server system, and download the files. You should probably run that as administrator... I did put a note on that, near the top of the main website page
Some people are having issues with various anti-virus programs, that say the client, or the updater, or even the plane builder... have a virus in them. I can promise you they do not. If you have that happening, you may need to exclude the dbs program folder from being scanned, or add in file exclusions for the various EXE files.
