Can't Seem to Solve This Issue

[CalleSevix]

I'm fairly new to modding and have came across a problem that I can not fix. I'm attempting to make a pixelmon server with my friends and minercaft keeps crashing when being launched from forge. 

If anyone can explain what's going on and how to fix it would be really appreciated!

This is the report:

Pixelmon isn’t working, it could be a pixlemon<->spongeforge incompatibility
