Hello! I love Tekkit but there is a problem. I hired a server and i've received an email that Tekkit will be avaible on my server. After a while i clicked for Tekkit Mod and installed 1 mod on it. The Mo's Creatures. I launched Technic Launcher and filled the IP of my server, but the server wouldn't do it. It says connection lost. Can someone please help me because i love to play mods with my friends!
