I do not think Panasonic has posted the new software for download yet. I checked and only see version 1.59.
As you probably already know, this model has built-in wireless and wired ethernet capabilities. Is there any way you can connect it up to a home network?
The download did not take very long for me (5 minutes) and it went without a hitch.
If not, I suggest you contact Panasonic customer support.
