You have eto use the auto update facility within DSDPlus FastLane (use the pull-down menus - the auto update feature is in there and needs checked). You can tell it to download the latest version, and then you'll have to use the password from your 228 email to open the archive.
If for some reason things don't work for you (FMP mismatch), then at that point email
dsdplusfastlane@gmail.com and ask for a full update.
But, in the future make sure you save all of your emails -- and make sure you have the auto-updating enabled in DSDPLus. It will check the server for a new version and provide you with hte opportunity to download it when it is available.
