Minecraft Forums

I've been trying to get a few mods working on my minecraft but I can't seem to run worlds properly.

I can load my client perfectly the only time it crashes is when I try to interact with anything in a minecraft world (modded or vanilla items/blocks).

I couldn't find any help on the internet for this so I was wondering if anyone on here could assist me?

Here is my crash log, I apologise if it isn't done correctly or whatever, I haven't done anything on these forums before:

Thankyou if you have any solutions!

ThanksI'll try it!

It works now, however I'm also trying to run a server and I don't know what I haven't set up properly.

I made a batch file to start my forge server and it starts fine but when I go into creative there aren't any of the modded items. Can anyone else help me with this?

Another issue, this time with my client which I am trying to run the mods on, this is now in 1.7.10:
