Using the 1.4.6 version with no problem at all. Install went as smooth as glass. Simply installed this version over my original 1.? version.

I had no problem with this upgrade just left out the shipping because its so darned confusing. Google made this part of their feed very difficult to set-up, and in my opinion very useless. Most of the sites that I have been on spell out their shipping better than you could on the Google site.

One other thing - if you previously had a feed set-up make sure you use that in your configuration or if you are going to do a new one delete the old.

Just an opinion.
