[Game wont start.]

Hello,

Whenever I want to launch the games, it closes the launcher as if it's launching the game. But it relaunches the launcher. I have tried to reinstall the Game and Launcher.

[Skin in multiplayer not working.]

Whenever I launch Tekkit Legends. My usual skin shows up on the main menu on the right, and shows up correctly in singleplayer. But whenever I go onto a multiplayer server, my skin goes to a default Steve skin. Once I go back to the main menu it shows as my skin again.
