so I recently downloaded the FTB launcher today and also got FTB Revelations, I'm on the starting launcher for the mod pack (like where the version/mod pack is in the bottom corner and the play button) and when I click play in the upper right-hand corner it says "Sorry, unable to start Minecraft. Please check configurations" now being i recently downloaded it I don't know anything about this launcher and what I would need to change or what to configure.
Other notes: i have the twitch launcher downloaded on here in case that might be bugging it.
