troubling installing office 2007

[gc]

I bought office 2007 last night for new laptop and downloaded it iinstead of
following links in pre-installed trial version. After installation only the
trial version was available. I uninstalled that, rebooted and the top
banners on docs and xls said (trial) I unstalled office, rebooted,
reinstalled and rebooted but the banners still say (trial.)
Because my printer won't work with vista, I didn't get a copy of the
confirmation, but I did capture the page with the product key.
Who do I contact to begin all over again?

You have to uninstall any Trial version & the Activation assistant before
installing any paid for version
