1.6.4 mod installed. Pay attention to what you're putting in the mods folder.

And use spoilers.

Actually it appears as though it's a 1.4.7 mod...

Hang on... I got to the 2nd line and:

Description: There was a severe problem during mod loading that has caused the game to fail

Dude, just play without mods.

It seems to be from this mod: cpw/mods/fml/common/ITickHandler

Also, from what the above 2 people have been saying, it sounds like your using a mod for minecraft 1.4.7, yet you say your using 1.7.10, and that means your using a mod that is for another version of minecraft, and therefore the mod is incompatible. You have to either:

a) delete the mob

b). UPDATE the mod, or

c) use the version of Minecraft the mod was intended for.

Dude, just play without mods.

Why would he do that?

So,
1. He should stop using mods because he accidentally put an 1.4.7 mod in? I fail to see why.

2. That's fml. It's not fml's fault.

Ok. let me try removing that stupid 1.4.7 mod. Thanks a lot. i didnt see that. oops.

Thanks alot you guyz. All of you helped me. Now I can play minecraft properly. But i liked the 1.4.7 mod but it is unusable for me. are there any ways to convert the 1.4.7 mod to 1.7.10 easily bcoz i am not so expert of converting.lol . Are there any apps/ways to convert the mod. Thanks

Well ok then. Thank You so much

This topic is done!

What I meant is he should stop using mods because There was a severe problem during mod loading that has caused the game to fail, although I wrote that part before looking further. And besides, I don't use mods and I get along fine.

As for Maevinarsh, your welcome! Glad you found a solution!

I still don't see why that means he shouldn't use mods.

Then why are you posting answers in the modded support forum?

He shouldn't use mods because mods are causing him to crash. And I didn't even know this was a modded support forum, I just clicked on a link in the active topics tab on the homepage.

Quote from ChaosTheDude»

Most crashes are solved easily - this one was, just a version mismatch. That doesn't mean he shouldn't play with mods.

Well at the time I only knew that a mod had failed to load or something causing a crash, so therefor he should stop using that mod. What's wrong with that?

Yeah Mods make my Minecraft sometimes to crash

But I like mods bcause they customize my Minecraft and changes minecraft to be funner to play. Playing normal minecraft is boring.

I just wanted to know that are there any application to convert that 1.4.7 mod to a 1.7.10 mod?

If no, Can someone (a java expert) convert that 1.4.7 mod (CameraCraft) to a 1.7.10 mod and give me the link to downlaod the converted file? Pls?

Thank You everybody for helping me to find a solution.

Unfortunately, no, there isn't.

Unfortunately, also probably a no, because:

1. That person would need the source for the mod, and I don't know it that's available.

2. Updating mods is a long and painful process, you would have a hard time finding someone to update it for you.

Ok then. I will find for mods that includes cameras other that Camera Craft. Thanks!
