My 2010 XK had version 2.043... from over a year ago. The next update was done in May 2010 after the last XK's were built (I believe)... not positive on that, but either way, this is newer and addresses some issues...
2.401 zip download
2.401 ISO download
I found the ISO very easy to use. I saved it to my hard drive, then When I single-clicked on the file, Windows 7 allowed me to burn the image on a CD.
Once the disc is burned.......
Do not attempt to install WITHOUT THE MOTOR RUNNING!
If the MyGig looses power at anytime during the install you can forget about the MyGig ever working again!
It is VERY IMPORTANT
to read the following instructions before you attempt to install. Failure to read could turn your pretty MyGig into a useless brick!
What ever you do --- do NOT
remove the disc till the MyGig asks you to install the software a second time! This is the equivalent of the "Your installation is complete" window. Then you simply click "NO" then you can eject the disc.
