can anyone help please?

Hi

 

Show your full error log?

 

Are you registering items or blocks with a fixed ID, by any chance?

Hi

 

Please post your ScienceCraft.java:362.  It appears to be trying to register the Block incorrectly.

here you go:  http://pastebin.com/7GK08w0L

"The object net.sciencecraft.machines.Grinder@7c1f7ea has been registered twice for the same name ScienceCraft:GrinderIdle" could this have anything to do with it?

Check out line 207.

If by any chance the error could be caused by an id you set for your block and something in minecraft already has that id things will not work. You do not need to set an id for your blocks that can make problems with other mods forge will auto assign an id to blocks an Items. Here is an example of a mod I made I do not give ids forge does that for me. I only posted the code for one of my items but you can get the idea from one. I also posted code for a diffrent mod I made that adds new blocks. Again I only added the code for one block.

He is using 1.6. Thats why there are ids. But he should update to 1.7.

Does anyone knows an answer yet?

Yes the answer is simple. Update to 1.7.10 then come back if you have any more trouble.

If you are doing 1.7 then you are doing things very wrong you should not be using id,s in 1.7+

Does anyone knows an answer yet?

Dude!

The error log says:

ScienceCraft line 362:

362:      GameRegistry.registerBlock(GrinderIdle, "GrinderIdle");

 

Search code for "GrinderIdle" gives, like I said in my previous post,
