I just recently found this and trying to use it. I have installed the file as your instructions say but my Launchbox is not showing "Missing Games Checker" as described in this post. I am using v13.22 and the LBMissingGamesCheckerPlugin.dll is in the \LaunchBox\Plugins directory. My Tools menu looks like the pic shown. I have also look at the sub selections of each to see if it was in any of them. Any help would be greatly appreciated. Thank you
