"active layer grid is locked or invisible"


I recently dl the trial version of CorelX4 and was creating a sign. Somehow I must have locked a grid because that is the error msg I get when I try to create more lettering. I can see a red circle with a line through in the object mangers box on the right. It won't allow me to "unlock" the crayon for the GRID which is lit up red. How do I reverse whatever I inadvertently have done? I can see page 1 and masters page. I can lock unlock other items but not the grid? Any help would be most appreciated
