thank you for the comment its the right mod pack, there are a few things wrong though i managed to get on it a put my texture pack on then it looked nothing like my texture pack and looked like bright squares everywhere, and now it wont even let me on the options page it just freezes at the mojang screen sends me back to the Technic launcher.

[Help]

basically i just downloaded tekkit. i saw on youtube you can go on the moon, i tried to do this but i went to make refined iron and i couldn't make it also i haven't got the maserator or the generator any help please.

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

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
