Whenever i would use mods in general like forge or technic, (in this case only forge) I hit play in minecraft for my forge installation and it starts up onto the screen before the minecraft home screen loading in all the mods and right before it finishes it crashes whenever it would be finishing. I appreciate the help here is the crash report:

 Pixelmon requires a specific version of Forge (specified on their website) but does not properly represent this fact in their actual mod file, so Forge cannot produce an accurate error message.

 

Please report to the Pixelmon authors that their mod is broken.

thanks for your help

For now, remove the pixelmon mod.
