XPath Expression Wizard Error
When I try to use the Wizard to help create a regular expression to remove headers/footers I get the following error:

Code:
ERROR: ERROR: Unhandled exception: <b>WindowsError</b>:[Error 6] The handle is invalid

It would have if you also gave the expression you were trying to use.

That's the thing. I don't know how to write an expression so I was hoping that the wizard would help create one.

I have a PDF I created a while back from a Lit file using the ABC Lit converter. I lost the lit file when my old PC was formatted.

The header is "Generated by ABC Amber LIT Converter, http://www.processtext.com/abclit.html"
And the footer is "Page x"

I'm using Calibre v0.6.30
