inDesign CC crashes when updating document headers Power Headers Forum

Huy guys, running the latest Power Headers with Indesign CC on Mac.

Have added a variable in my header, I can see the variable name ok, but it's unitiated. So, I press Update Document Headers and after a few seconds InDesign crashes - just before it goes down there is a Power Header dialog box showing a progress bar, as it gets to the end InDesign crashes.

At first I thought there may be something wrong with my doc, but same thing with a new doc.

I tried reinstalling Power Headers but same result.

Guessing I'm doing something wrong.

Any pointers for me?

OSX Mavericks, InDesign CC (V9) with all latest CC updates.

Many thanks,

Chris
