Updating to current CSI codes

My company is still using the 16 division CSI codes in Sage and I'm trying to figure out how to update sage to the current CSI codes.

I'm finding that you can use the Means Integrator to update this, but it requires RSMeans Cost Data files, which I can't find a download through Sage. Is this a separate purchase or is there a way to update the Sage CSI codes without changing our cost data?
