Make sure you use a download manager when you download your 09,
Use a Download Manager (e.g. www.GetRight.com) to speed up downloading the full 2.6GB version (if you ordered the digital download version). Install TS2009 to a new directory (i.e. keep your previous installations plus you existing content separate from the new version). Copy and paste your serial number to avoid entry errors and register your serial number with Planet Auran so it is kept in a nice safe place if you ever have to reinstall. (Tip: In Planet Auran, go to Order History and click on your Serial Number. This will open a new window. Click Submit to register).
