Windows .exe Game crashes when attempting to open GUI

[paradoxbomb]

FTB Launcher version:1.2.4

Minecraft Version:1.4.7

Java version: 64 bit, version 7 update 21 (build 1.7.0_21-b11)

Detailed description of the issue / how can the issue be recreated: Have been noodling around with some new mods lately, but I've never seen this type of thing before. As soon as I press "e" or try to right-click on any chest, furnace, or pretty much anything else that would have a GUI, the game crashes. I am playing and running a server on the same computer, in case that is relevant.

Here are the simple instructions: You need to delete the NEI folder and NEI.dat inside the individual save. The NEI folder and NEI.dat that is outside all the individual saves, but still inside the saves folder you can also try deleting if deleting the first two does not work. I've been told that deleting the other set it is not needed.

This is caused by a few of the mods, namely xycraft so far is the only one that is known for sure, causing this error with NEI. Check here for more info if you are interested:

Edit: This error is not game breaking so do not worry about disabling xycraft because of this.

That seemed to do the trick. Thanks!
