I bought a copy of Microsoft Office 2007 for $79. I downloaded the software with no problems, entered the license key they provided with no issues. the product ran fine for a couple of weeks until the products (Outlook and Word) complained that the license I was using was not valid. I ran the Microsoft validation tool for Office 2007 and it reported that I had an invalid license. Customer support tried to help, but they finally gave up and so did I. I went to Fry's and bought a legal copy for $240.
