Coloured image

When I open my image, it comes up all coloured.  I can get rid of it by changing to 32 bit, but then when I revert back to 8 bit to save, the HDR box pops up and it changes the look of the image automatically on me.  HELP

I am shooting with a Canon 5D Mark II, in RAW (SRAWI).

The guy on telephone support got rid of it temporarily, but next time I opened the program, everything was messed up again.  He claims he just reset the setting to default, but I made NO changes to the settings following his intervention.
