Tekkit closes and goes back to the laucher after the mojang screen.

[MVSSENJU]

Please help me! I've searched in all internet, but i can't find the solution for my problem.

 

So, I open the launcher, I log-in, I click in the tekkit, I click on the "play" button and the mojang screen apears, but after it the tekkit closes and it goes back to the laucher! Please help me!

i had this problem im not sure what caused it but the way i fixed it is by deleting the tekkit file in the app data. you can save your game save to a different place and put it back later but just delete the other files and then redownload them it should work
