I repacked the zip, this is the latest one. It was double-checked that the shop issue was fixed with it. If it doesn't I suggest you to wait for someone to post the newest full update, since that's working, and to load a save prior to visiting the shop.
I used 7zip to zip the file.
Can't help you more than this, since now the game's working (it should also fix the broken save if you followed my instructions I posted earlier, but I can't guarantee it I'm only guessing given the behavior on my machine).
