Hello. I am new to the server/moding world. I have DL'd the premade Tekkit, Tekkit Classic, and Moonquest server packs. I have gotten the Tekkit server pack to work by simply starting the .jar file. I can not get it to work with the others. When I double click the .jar file. It just loads for a minute, but nothing happens after that. What is my noob brain doing wrong? Thank you, Shas
