Can't play.

[RoonsterMan02]

I turned on my computer this morning to play some B-Team. Opened the launcher. Over half of the base modpacks have gone missing, and when I attempt to load any of the ones there the game crashes before getting to main menu of Minecraft. How do I fix this?

post the log

logs can be found when clicking the Cog-Wheel button on the top right corner on the launcher window.
If you can't open the launcher the logs can also be found inside %appdata% -> Roaming -> .technic -> logs
