I just downloaded the launcher, and tried to start up Tekkit, it asked if I wanted to update to the most recent update, naturally I agreed. It kept telling me that Mods werent compatible with this update, and that I had to manually out the newer versions into the mods folder. After doing this it told me "Minecraft cannot launch in its current configuration" and to consult the log for further information. I didn't understand the slightest thing off of it, so I'm asking for help. Here is the log

If anyone knows how to fix this, please tell me
