Wait. It just started working. In trying different things, I turned off my VPN to see if that was the issue, and it appears that it was. Before, when I attempted to access the server, I did not see these two icons down at the bottom of the screen - they obviously denote the mods that are loaded. Turning off my VPN apparently opened up my system to activate them, load them, and use them.

Naw, no dump files. That's all of them. Here are the two mods that I need to use for the server that I want to join.

I get this error message when I unload all mods.
