Socket Error/ Vassal won't load module

I’m running on a new MacBook Pro. Just installed Vassal, and some modules. When I load a new module within vassal, vassal then attempts to load the image tiles. Once the image tiles loads to 100%, nothing happens. I wait for a few minutes, still nothing happens. When I quit the module, an error appears (images will be attached of error code), with the title reading "The socket over which the Module Manager communicates has had a fault. Please restart VASSAL.

I’ve checked my firewall, it’s off. So no fire wall interference. I don’t understand what would be the issue. Anyone have any ideas???
