OK,
Being the devil may care living life on the edge sort of guy I am, I've d/l'd and installed the upgrade.

The actual installation takes about 15 (tense) minutes hoping for no power glitch.

Here's something else you might watch for.....I double clicked the file and what I got was a black box that looks similar to the MS DOS prompt box....

Near as I can tell, it is just a dialog box asking if you want to reunzip the executable file that is already there....so answer n (no) to this, because the file is there.....so...

Make sure you close your Windows Explorer and reopen, so that it refreshes and you can see the installer icon. Once you see that which they are referring to on the pk site above it's real straight forward and comes off just as the instructions show.

The Tyros screen will go blue and tell you to wait awhile. When it is done, both the Tyros and the PC will tell you it is completed. When you're staring at the screen on the PC wondering if it's locked up or really doing something or not....watch on the bottom left.....it will say "load data" then it'll say "writing block" as it u/l's the stuff.
jam on,
Terry
