Sounds like you are missing an updated driver perhaps? Check on the Utilities console app, and see if it copies the drivers locally (the properties panel in Visual Studio when you select the driver on the content tree), if this is the case it may be still referencing an old driver. Otherwise verify it's pointing to the updated V10 kentico drivers, try cleaning the solution, and also check the files themselves and see if there is any driver that is being used over the proper one.
