There is no direct way to download 2014.0, so you need to do a trick to get the DMG file.
You need to download CC2014, when you are downloading watch the /tmp folder (finder/go/go to folder)
watch the folder around 50% download you will see the DMG files appear, drag the DMG file to another folder and stop the download.
That is cc 2014.0, Adobe installs the 2014.0 first then updates, so if you don't move the DMG file and stop the install adobe will delete the DMG file after it install it.
then updates the program to 2014.2.
You can get the 2014.1 update here

Works great for me, Save the DMG files to disc for backup.
