Hello,
They changed the syntax to the filterCurve command...(I played around with it and just luckily found out thats what it was). If you download the linked script and place it in your scripts folder so it sources at startup it will fix your problem.

the script had a bug in it, it was a bit trickier than I thought to get this fixed. It should be all good now just re-download.
