Installed the new Sony software 3.1 on my Windows 7 HP PC. It acted strange while installling. It downloaded multiple copies of one book. It crashed my Windows 7 PC while transferring books to my PRS-300, and now the PRS-300 won't work. What a POS Sony!!!!

EDIT #1:
It did nasty things to my PC, including trashing the WLAN connection, so it has now been uninstalled. My PRS-300 is still unable to work. I'm furious at those Sony idiots!!!!!!!!!!!

EDIT #2:
I finally got my PRS-300 to work again. It took four resets and over an hour. I installed the new reader software on a Win XP netbook and it works, albeit it still is downloading multiple copies of some books. I like the ePub replacements to a few large books that took forever to open in BBeB format. The ePub files are half the size and open much more quickly. For a novel, this is not that important. On a 6MB file it is very important.
