Hi, where did you get the disc? What is the software version you were at before the upgrade? Was it 3-1/63? That is the latest for MKIII. There have been no changes to the MKIII OS since version V22... so any update disc after V22 will not really do much for you.
Can you tell us what you expecting to see with the V27? MKIII display does not really have any visual updates like perspective mode, etc.
