Don-
Ironically, I just experienced a similar problem this evening - the first on my 10-mo.-old K2. My unit froze and I performed a successful reset -BUT- it resulted in "most recent first" books being added to the last page (18)!
I can confirm the solution by the clock reset method. I enabled Whispernet, performed a sync and all is normal again. So... as soon as you plant your feet on U.S. soil just activate the wireless, sync and you should be set.
Have a safe trip!
