How do I invite my players to my table created in the System Builder?

I have invited my players to my table created in the System Builder, but when I log in as a GM from the My Tables link to access this table, Let's Role shows me a black screen and the game is not working!

This seems to confuse more than one system developer. The Table that was created in the System Builder (easy to recognize, its name starts with [Builder] if you haven't edited it) was created for testing and simulation purposes, so it is not operational outside of it.

Consequently, you should not invite players to connect to it, as it will be impossible for you to connect to it yourself as a GM from the Let's Role site > My Tables. This will inevitably result in a black screen.

Prefer this solution: create a table outside System Builder to test my system with my players.
