MC 1.4.7 - mod crashes with Incompatible Argument

[Lycanus Darkbinder]

I posted this on the mod author's minecraftforum page but he said he doesn't know what the error means and doesn't seem interesed in fixing it since he's moved on to Minecraft 1.5.1.

I have a basic idea of what the error is but I don't know how to fix it. I used BON to deobfuscate the mod so I could give the author some suggestions but there are still some functions that use obfuscated names so Eclipse can't resolve them.

 

Example:

 

return par1World.k  - Eclipse doesn't know what "k" is

CallableLevelGenerator.d  - Eclipse doesn't know what "CallableLevelGenerator" is

Typically this is caused by you not using the proper version of Minecraft for your mod.

Do you mean as a developer or user?

 

I've tried looking at it in mcp725 (for mc 1.4.6), mcp726 and mcp726a (for mc 1.4.7) and I've also tried loading the mod as a user in MC 1.4.6, 1.4.7.

 

The author's 1.5.1 version works in MC 1.5.1 so I was hoping to be able to offer help fixing the 1.4.7 version since I'll be staying on it for a while as I wait for other 1.5.1 mods to work out their bugs.
