Help with an error log after the new "update"

[primalcraft]

I knew that updating probably wasnt a good idea because something like this might happen. soooo I updated my launcher and now when it starts minecraft it crashes and gives me this message.

I get that it has something to do with block ID's but i have no idea how to fix it.

I deleted my launcher folder and re-ran it. Seems to have worked but what the heck happend?!

Does it hurt people to look before they post? Goddamn son. Its a Technic issue and not a Launcher issue yeah? The launcher ran just fine.
