What am I doing wrong? Error: "Sorry, but no pictures were received from Picasa"

I recently installed Picasa Album Uploader but have yet to get it to operate successfully. I’ve set permalinks to “custom structure: /%postname%/” and I’ve installed the button in Picasa 3 successfully. But, when I select a picture and login through the pop up window I always get a “Sorry, but no pictures were received from Picasa” message. What gives?

I appreciate everybodies time and consideration!
