Have you checked that your stacked TIFF from DSS is a valid file? Check the file size - I've noticed that when something goes wrong in DSS (runs out of memory, some kind of internal problem, etc) it will save an output TIFF file that's only 8 bytes! That might be way Photoshop can't open it, i.e. it's not a valid file.
By the way, I've found that I get better results using DSS to do the linear and non-linear stretching, since Photoshop CS5 can only perform "curves" on 16-bit data but DSS does it on 32-bit data.
