Yea, that looks like you have two Arms and Equipment Guide user files present. There is no reason that the latest release would cause that on its own. Did you change the name of a file? Another possibility is that you missed a release somewhere in between. If you have no custom .user files of your own, you might consider removing all .user files and re-downloading the community set. If you decide to do this, I recommend saving all your current .user files in another folder so that you don't lose anything you or someone else may have put in there that you forgot about.
