norton 2009 - 60 day download / no contact details

Hey! I just purchased Norton 2009 as a download...

I didn’t get the extended download as I am more than happy to put any install files on my computer and burn to CD etc.I have just found out (wasn’t mentioned before) that a very small file is used to download and install the Norton 2009 files. Will this file be enough to start the Norton 2009 installation in the future if I choose to format my pc? I am a tad concerned that there are no longer contact details for Norton without paying additional money for "professional support" - can anyone let me know if this very small file (setup.exe) (660KB) will allow me to reinstall after the 60 download period?Many thanks!
