Adobe Premiere Elements not updating from 13.0 to 13.1

When I start the program, I get the info box that tells me about the latest update and gives me a button to click that downloads and runs the update program. I do that, and the update appears to download and go through the full update routine. However, when I start Adobe Premiere Elements 13 again, it gives me the box about the update, and the software is still at version 13.0.
