Can't get past Cider's loading screen

When I try to start any kind of server running the Cider gamemode (the apparently “shitty” one that was released long ago), I can’t get past it’s loading screen. I just want to try it out. It says “Jump to rejoin if you are stuck on this screen!” I do that, still doesn’t work.

What’s interesting is that I can move, fire my weapon, spawn props and shit, but I can’t see anything but the message.

Any solutions?

This is normally because your MySQL tables aren’t set up properly or aren’t linked to your server correctly.
PM me on here and we can discuss this through Steam as it’s easier to communicate and hopefully I can sort it all out for you.
