Remove the X from discontinued Koji Advance Plugin

Hi, so I recently came across Koji Advance, a plugin for color grading and film emulation. Apparently, the plugin has been discontinued a while ago from FxFactory, but I found a way to download it and install it. You have to have FxFactory installed in order for the plugin to work. But when I installed it, I can color grade my footage just fine but I have this huge, red X on my footage.

I tried to reach out to FxFactory but that is going no where. Does any one know a way to remove that X from my footage. If not, is there a similar alternative that is reliable but won't break the bank?

For an alternative, look at FilmConvert Nitrate, or the free BorisFX BCC+ Looks filter.
