Cheer up, I know it's Windows but did your download specify how many times you could install the software?
Nothing gets me angrier than having to pay extortionate prices for M$ software then being severely llimited in how I can use it. My copy of M$ Office for Mac came with three product keys, and I have three Macs in the house. Am I correct in assuming that I may as well throw the software away because it's now unuseable and unsaleable, or have I got this all wrong? I'll be upgrading my laptop later in the year and I'll be mightily pissed off if I have to turn around and pay these gouging bastards for another copy.
On a lighter note, that Vista Speech Recognition clip is a classic, but I can't seem to download it.
