White Color problem?!?!?

[User45]

I have a strange problem. I downloaded the tryout version of Adobe Photoshop CS2 but a strange things occurs. I don't have the white color as an option to select! Instead i have in its place only a light yellow and generally i can't use white color at all only some yellowish one. Also the images i load have a yellow appear....WHY?
When i go to Color properties with CTRL+SHIFT+K whatever i define i have the same problem except when i set RGB to "My Monitor RGB" instead of "North America,Europe 2 etc..."
While i could live with the RGB setting be at this and everything would be normal, i can't do it, since i want to know the reason that it doesn't work in ALL other options....

What is going on? Is it my monitor(LG L1930SQ) or is it because it is a trial version of Photoshop and have to buy the whole package?

Thanks in advance....

Your monitor's colors are off. It needs to be color calibrated. Photoshop has a tool which will do this on a rough basis. You'll probably find the name of the routine in the help screens.

Start > Control Panel > D-Click the Adobe Gamma Icon and follow the instructions to calibrate
