Launcher Launching Vanilla MC

[Exiledminer]

Hey Guys,
I deleted my FTB modpack because of some problems with another server, and I tried to reinstall it with the launcher, but now the launcher downloads the modpack, and only launches Vanilla MC. Thank you for your help!

logs please
Open the launcher and to the Options tab. Ensure that there are checks in the boxes next to 'Show Console?' and 'Reopen launcher after exiting minecraft?' Then when you get the error if you have to close minecraft the launcher should reopen and allow you to click on the 'Paste my log to pastebin.com' button. This will add a link at the bottom of your console post that link here so we can see your log.
