Using the "forge pack" launcher I believe was provided on this server's page, I've had little to no problems booting up the pixelmon client for this server until today, the launcher as of today has failed consistently to boot up the game. I receive the usual "game started" prompt, but nothing afterwards. Typically the window of the launcher is automatically hidden, and the game window pops up without any problems, but no such luck today. Any advice?
I just tested it myself and it booted up just fine for me. Try to wipe all data in forgepack settings, close launcher and then redownload the game maybe that will help
