Raster Pyramid/statistics issues

Hello, I'm having problems with some raster layers (aspect, slope) that last week I was able to change the colour ramp in the Classified tab, however opening it up this morning, the drop down menu is entirely blank. I have tried recalculating both statistics and pyramids to varying degrees of success;

1) In some times get told that statistics have been calculated yet no statistics show up in the source tab

2) In trying to build new pyramids I get an error warning that as the pixel size is less than 1024 x 1024 pixels it's unable to calculate a raster (how to do you deal with this issue, I have not found this issue anywhere)

3) In another case, I have both statistics and a pyramid but still no drop down menu to change the colour ramp in the classified tab

Any thoughts as to how I can get my colour ramps to return would be greatly appreciated
