Try renaming/deleting your game data. For Windows 7 do the following:

Navigate to C:UsersusernameAppDataRoaming (where C: is the drive letter you installed on and username is your Windows username)

Rename or delete the .minecraft and .technic folder

Relaunch the launcher and select which modpack you want to use and version
