I had actually purchased the home premium upgrade for another machine, that died before the upgrade could be installed. I bought the pro version for my main PC but had trouble with the initial install because I was not running the pro version of Vista x64. So, now I am hoping that since I got the home premium up and running, that if I install the pro upgrade, it will work and I won't have to reinstall all my programs (as it wanted me to do originally).
In the meantime my laptop, that was running Windows 7 Home Premium had some kind of registry error and prevented the windows update from working and installing updates properly. It wouldn't let me install the SP1, either. Long story short, I tried to repair it with an upgradse version and my original FPP, and needles to say, it is majorly "F-ed" up. I have now resorted to using my recovery disc to reinstall the factory version of Windows, so this post is probably moot anyway. Since it was my laptop, I didn't keep many or major files on it and I backed up anything that I will need again. I just really didn't want to have to do the tweaks again.
I also was able to purchase both programs through discount programs, (and, they were HIGHLY discounted) so the money issue is not really a problem.
