How to show Mcsft that my Office 07, single seater, IS genuine?

In May '09 I bought a download of Office '07 from an apparently authorized
source, a Mcsft software engineer, for my solo law practice. In September I
started getting "this copy is not genuine" messages. My seller tells me the
problem is with Mcsft single-seat licenses like mine and has offered two
fixes, neither of which works. My program still works, but with "Not
Genuine" messages; I'm concerned that no fix has come from Mcsft and that it
may shut down my practice.... Help!

Does download refer to the internet, or physical cd?
Volume licensing starts from 5
