For sure, here is the class using this TileEntity:

}

{
	topIcons = new IIcon[blockInfo.PIN_TOPICON.length];
	for(int i = 0; i < topIcons.length; ++i)
	{

	}

	sideIcon = reg.registerIcon(BlockInfo.RESOURCE_LOCATION + ":" + BlockInfo.PIN_SIDEICON);
}

@Override
public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase player, ItemStack item)

	TileEntity te = world.getTileEntity(x, y, z);

	if (te != null && te instanceof TileEntityPin)
	{

The exception tells you exactly what went wrong: your

TileEntityPin

class doesn't have a mapping. You need to register it with

GameRegistry.registerTileEntity

.

 

Side note: Package names should be all lowercase.
