Minecraft Forums

Ok so i downloaded pixelmon 2.5 and forge 9.11.1.916 and installed them both, when i start the launcher up i go on the forge profile, i make sure it is usuing forge and then i press play (online) , and the launcher shuts down and nothing happens. I've re downloaded everything, i used different versions of forge , and i get nothing. I do believe it is forge tho because when i take the pixelmon mod out of the mods folder nothing happens, and when i delete forge minecraft works just fine. Any one going through the same problem and/or no how to fix this. i get no error it just shuts down. Also would it be more helpful if i added screen shots or video to this?
