Update Failed.

I was using the Catchupdater to update Kathmandu to 4.4. I successfully did so on several other installations today. However, on this one I am getting error messages: Unpacking the package… Installing the theme… Destination folder already exists. /hermes/bosnaweb03a/b2079/ipw.coastalvisionblog/public_html/nerdt/wp-content/themes/catch-kathmandu-pro/ Theme install failed. I am running WordPress 4.3 What do you advise?
