The proposition of meeting up with some one they don't know online to discuss getting paid for something that could be potentially illegal (depending on what it is you are hoping they do) is a risk most people refuse to take. There are enough guides and people willing to help here on the forum you'd be better served just asking your questions in the appropriate forums.
Could you follow the steps Koroth provided and let us know what your application path is. From there may be able to help you figure out what is going on.
Bit confused as to what you are seeing. If you have a recent backup (.7z) in your Backups folder you can just extract it to \\Launchbox\Data\ and it should be doing the same thing as the restore via LaunchBox. This all needs to be done while LaunchBox is CLOSED.
Unsure what would be causing this at the moment but can look into. Do you have the power settings on your controller enabled (are on by default)? May help to disable those. May be that your controller port is shut off when first loading, and isn't for subsequent launches.
I do this with my collection for genre's and series. Just change your filter view to Platform Category, then create a Platform Category called "Genres" (or whatever you want it to be). Set it's parent to be the root. Then add playlists to that category for each genre (or whatever field you are doing it for).
Make sure you open Launchbox and turn on debug logging, that will give us the most useful information to attempt to help you out. Also would help to know what OS you are using and what LaunchBox version.
In the page that lists your game, push Ctrl-A to select them all, then right click and mouse over "Set Platform". You can pick between MS-DOS, Windows, and GOG or set your own platform.
At the top of the web page click "Help & Support" and then "Request a feature". Unsure what all is available for us to use as a way to tell that. Interesting idea though. If you could use the feature request people could vote on it and we could see how many would benefit from it.
Do you have any of these issues if that plugin isn't used? Curious if the plugin is manually changing that field to match whatever settings you told it to use.
Can you reinstall over top your existing install. LaunchBox is having issues loading the DLLs it needs. Doing this won't affect your data at all. Just makes sure you install in the same directory and don't accidentally create a LaunchBox directory IN the LaunchBox directory with the installer (\\Launchbox\Launchbox)
Inside of Steam. In the Main UI you have the headers Store, Library, Community, and then your profile name. Click the profile name. On the page that loads on the right there should be a link that says "Edit Profile" click it. Should bring you to the page you need.
