At the begaining of this year I posted about a "sanity check LUT failed" error message when i tried to run spyder 3. After contacting Datacolor reloading and upgrading, no fix. With the help of a POTN member tried unloading and reloading the Radeon Hd 5700 display adapter, no change. Seams the problem may be the operating system. I decided to hold off reloading it untill last week (work related reason). I took my harddrive a Dell dimension i7 into work and the I.T. department tried to run a couple of internal fixes. than tried to run the spyder using there monitor, same error message. Imaged the system, reloaded the operating system and than loaded the spyder 3 and upgraded to 4. Ran the spyder it worked. Took the harddrive home loaded PS5, Lightroom3, windows works and logitech. ran the spyder to calabrate my Dell U2410, and I get the error message. So thinking it was the logitech I tried to uninstall it and than run the spyder, error message. I went back to I.T. reload OS, PS, lightroom and works then the spyder 3 and upgraaded to 4. Still get the error message. Have a Dell SE198WFP monitor tried the spyder on it same error message. The spyder works on my Dell laptop and it has the same software. Its probably all a waist of time since i'm partialy color blind, but if I have the tools to do it right then I would like to at least try. Not much on giving up. Is thier another color calibration system that will work with my system? any way to rent it first to see if it works before buying?
Sorry about the long rant.

(not reading closely). BTW, I was not "giving you a hard time". I simply wanted you to know I was not insulting René but merely "cutting up".
