When I load a raster Tiff image (with Pseudo color), and try to open the attribute table, an error pops up saying "No raster attribute table. Compute stats on layer using image info." even though the layer definetly has attribute table with different classes in it. Can anybody please tell me what is going on here? this happens 80% of the time when I try to open the image and suddenly some times the attribute table shows up. I am not sure what is causing the problem.
Any help will be greatly appreciated.

Did you try recalculating the image statistics using the Image Metadata tool (ImageInfo)? Open the Image Metadata tool by going to
ERDAS IMAGINE > Home tab > Information group > Metadata menu > View/Edit Image Metadata. In the Image Metadata tool click on Edit menu and select Compute Pyramid Layers/Statistics. In the Pyramid Layer/Statistics Generation Options dialog turn on the Compute Statistics option, set the X and Y skip factors to 1 and click OK. Reopen your TIFF image and open the raster attribute table.
