The first thing you should try is to re-install the update...and or re-install 1.04 if that doesn't work.

Version 1.04 has just been re-installed. No problems doing that.
After that, I turned the unit On and Off like 6 times and everything was just fine.
I'll try again in the morning. Anyway, my R-09HR was freezing all the time and now it is not.
Since I'm not alone dealing with this problem, I assume there is something wrong with this 1.05 update.
It would be great to listen from other folks.
