We didn't make sui_scoreboard, and this forum area is intended for ULib and ULX only.
Though Megiddo did fix a few things of one, it would be best to ask in the actual release post.
Please look in the releases section of the forums... several scoreboard versions are there by different authors... read the first post of the one you downloaded and if the instructions aren't in it, or within the download file as a readme, then ask in that release.
