Keep getting this error

Before the 1.5 update I had an error upon trying to launch my mod, and I was unable to fix it.  I am getting a different error after the update.  Here it is:

You might want to give us your code, and it seems like the error is from your class not found.

 

A few questions:

 

1) Are you sure you installed the mod correctly?

2) Are you sure that package includes the mod?

3) Are you sure that if you are using the in-game 'Eclipse' MC launcher you made sure the class had the right name?

4) Are you sure 'sonick.common.mod.TestMod' is the correct path?

 

[On the top of TestMod.java, you must have]

 

package sonick.common.mod;

 

@Mod(modid = "TestMod", name = "TestMod", version = "v0.1")

@NetworkMod(clientSideRequired = true, serverSideRequired = false)

public class TestMod

{ //if you extend or implement add that.

//then add stuff here

}

Thats is what I have, but here is the code:

 

 

package sonick.common.mod;

import cpw.mods.fml.common.network.NetworkMod;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.Init;
import cpw.mods.fml.common.Mod.PostInit;
import cpw.mods.fml.common.Mod.PreInit;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;

@Mod(modid = "TestMod", name = "Sonick's Test Mod", version = "0.1")
@NetworkMod(clientSideRequired = true, serverSideRequired = false)

public class TestMod {

@PreInit
public void preInit(FMLPreInitializationEvent event) {

}

@Init
public void load(FMLInitializationEvent event) {

}

@PostInit
public void postInit(FMLPostInitializationEvent event) {

}

}

 

 

Also this is all that I have right now because I didn't want to do anything else if it wouldn't work.

I added both @Instance and @SidedProxy, along with the proxy classes, and still got the same error.  Is it possible that there is something wrong with my forge, or even my computer?  I have been getting a similar error for a few different versions so this is very strange.
