Help?

Two things I did when I was testing my modpak mods.

1. Make sure all the mods for 1.7.10, I accidentally threw some 1.8 mods in and it caused crashes like this. Also make sure you have the latest version of Forge installed.

2. Take all the mods out, make sure MC with Forge loads OK. Then slowly add mods in and start MC. Make sure it loads fully, before quitting and adding more mods. I added my mods in by file name, aka, all the A mods at one time and test. Then all the B mods, etc.

Undeadlord

I will try that

Using a reverse version of the solution that you proposed Undeadlord I find the two mods that were causing trouble, but now I have encountered a new arror that I do not know how to tackle

any idea?

Yes I know but I do not know what that means

I know now that is the infamous Permgen memory error but where do I change the thing in the laucher?

so...... how do I fix it..... or can I fix it?

okay, okay, easy there man. forgive my ignorance and thanks for pointing me in the right direction
