Me too, so annoying, please reply

[Cheap Shot]

If it's a server error, you want tekkit bugs. If the launcher closes and the game opens it is NOT a launcher bug.

[William Elsender]

go into options in the technic launcher and click use development build, then itll update tekkit, should work after that. your friends will have to do the same too
