Having recently purchased a new LCD panel (HP 24″ S-IPS), I decided to calibrate it using my Spyder2Express.  So, I installed the 2.3.1 software, and immediate fail – it’s not designed to work with a 64-bit installation of Vista; Vista is less tolerant of unsigned drivers.  So, a bit of research, and I found I needed the 2.3.5 version of the software.  Downloaded, installed, ran.  What do you mean ’serial number’?  Hunted around, dug through paperwork piles, CD casings, boxes – nada.  Against all hope I filled in a form on Datavision’s site, explaining my dilemma and asking if I’d have to buy a new Spyder2 to get a new serial number (which I could do easily).  To my surprise, I had a reply within 24 hours, with a new key no less.  My display is now colour calibrated, and I’m trawling through 17,000 photos to verify the calibration.
