CMYK color Palette in CORELDRAW X3

Hi. I am hoping someone will beable to help me out here, a friend of mine is having a very strange problem the one day COREL's CMYK Palette colors were fine the next day he came to work switched on the machine and the colors changed to this really bright color. We have tried everything re-installing it, etc.... but nothing helps, any help will be greatly appreciated.

Color Management was turned accidentally off : Tools->Color Management and choose some of the preset CM styles or make your own according to your hardware/output devices.

btw, the "Toggle CM" button may be found in customization items in tools->options->customization->command->View-> "CalibrateColors" (you can put it in your standard toolbar, for ex. if you need to toggle the CM for some purpose such as rgb web development)

Thankyou so much that helped, appreciate it.
