In the making of my new mod I don't have any errors at all popping up in eclipse but when I run the client to test out my work and I get a Minecraft crash from this line that has no errors: 
  
 
HempSeed = new ItemHempSeed(7001,GrowersParadiseCore.HempPlant.blockID,net.minecraft.src.Block.tilledField.blockID).setItemName("Hemp Seed").setIconIndex(1);
LanguageRegistry.addName(HempSeed, "\u00a7AHemp Seed");
 
  
And here is the crash report to anyone that it will help:

In advance all help is much appreciated, Thanks
