Hey mate, I updated to the latest version towards the end of January and yeah it was a painful exercise - started out just wanting to do a few smart tune runs, had to check for updates due to not doing it for more than 30 days and several attempts later finally had it downloaded (issues with my antivirus blocking it) - the sort of good news is though that once you have it downloaded and installed, you won't ever have to do it again. The flip side is that it appears it won't be supported any more by HD.

Good luck, and may be worth making a back up copy in case your PC craps itself.

cheers
