I'm running the newest version of WP and Picasa I'm able to get the plugin installed but when I try to load the button into Picasa nothing happens. My computer downloads the file and opens Picasa but no button shows up in the button listing.
I'm running Windows 7 64bit, but I have no problems with other Picasa buttons I have installed (Facebook). The button doesn't appear to install into the buttons folder for Picasa. I've tried running Picasa in admin mode and it still doesn't work.
