Coreldraw 13 image color issue

hiya again,

i have a very large image of flames and i opened the image in corel photo-paint i then used the convert to CMYK command, then made the image 300dpi and larger. i imported the image to coreldraw and everything was fine… then the other day i went into print preview and tried printing… once i cancelled out of print preview the image color had changed slightly… it seems to have become darker almost illuminated…?

i have tried looking at the color management incase it was just looking like that on screen… but even when i print it now it prints the same way…

how could this have happened? can i fix it?
