OS: Mac
using minecraft 1.7.2
when i open the tekkit launcher it asks for my account and when i enter my info the launcher continues to the main screen where i select the newest tekkit and then instead of launch it has the button that says play when i click that it procedes to show a download bar that runs a bunch of zip files and jar files then it finishes and when i go to play minecraft none of the mods work. i was just wondering why i don't have a launch button.
