'Replace in File' Parse Error

I have a number of .TAB sql files in a folder that I want to replace text within.
I want to replace
CREATE TABLE [[dbo]].[[
with
CREATE TABLE [[dbo]].[[#
obviously to make temporary tables from script.
I am getting the error "Unmatched [ or [^"
If I just use one square bracket per position, ie using
CREATE TABLE [dbo].[
I get the error"Error expanding macros in property Find: <Error parsing scripts: Unrecoverable Parse Error at position 20 - expecting {section}>"


How do I do the above, Thanks, Mike
