We use that configuration here and haven't had problems lately. There was a period where they were fixing a few issues around the time that they started supporting our enroute charts, and also, there was a short time that they were publishing a version of the program before its general release. That should've auto-updated to the latest, but you can also always get the latest version at http://chartdata.seattleavionics.com/Apps/DataManagerSetup.exe. As of right now, the latest version is 4.1.4.014, which you can see at the bottom left of the ChartData Manager application.
