SScoreboard Error

I purchased SScoreboard a few days ago and as soon as I loaded it on my server I get errors upon pressing TAB (To open it)

I've opened a support ticket just a few hours after buying it and the maker has yet to respond despite coming online multiple times, which I don't blame him for, I just want this script to work, because at this point, I feel like I've wasted money on it.

I've tried removing ALL addons and reverting to 100% vanilla, and the same errors still appear.

Gamemode: ZombieSurvival I've also tested in sandbox to no avail

Any other addons that change scoreboard?: No

How to re-create? Press TAB while in-game

Errors?:

[ERROR] addons/sscoreboard/lua/sscoreboard/vgui/base.lua:310: attempt to index field 'Frame' (a nil value)

This error is also visible:
