Ok so I downloaded the FTB Beyond Profile. After that was done I created a new server and set the main stuff (name, difficulty, port, etc.). Then I set the profile to FTB Beyond that just finished downloading. I accepted the EULA and set the launcher to the FTB Beyond .jar file. I set the XmX and XmS and whatnot. When I press Start nothing happens. Absolutely nothing.
Only one time did I click start and it actually looked like it tried to start but it immediately stopped. Is there a way to see what is going on or why it will not even attempt to start?
OR is there something I am doing wrong in order to get this to work??
