I have installed Mo'Creatures to my FTB client along with my server, the server works fine and starts up and says it is live. When i try to connect to it without the Mo'Creatures mod it lets me know i need to install the mods in my client.

I do so with the correct 1.4.7 mods (the same ones i used on my server) and get the error below.

Looking at YouYube videos on how to install Mo'Creatures and following their steps, it seems this is a different Error than people normally get (the one where you have to change the id of some blocks that conflict)

I am using the Yogcraft Pack also for Server and Launcher Use. Any help will be great!

the error is above in the initial post, other than that that's all that was wrong in the FTB launcher console so i had to force exit it due to the black screen.
