I would say up to 2015, too.
You are dealing with quite a chunk of data, so downloading, unzipping etc., are going to take a while . From memory, I think downloading, unzipping and uploading to the sd card have each taken around 45 minutes. Could be wrong, but it’s not stupid long times. Be patient and don’t bale until you’re absolutely sure the process has failed. If you’ve followed the process correctly, you shouldn’t have a problem.
