Removing leading numbers from TITLE field

I've followed every example in the forum and support discussions. No matter what I do I can't get a regex to work on the TITLE field of an MP3 track. I'm running on 64 bit Win 7.

There are TITLE names such as

01 A Day in The Life
02 Yellow Submarine

All I'm trying to do is get this:

A Day in The Life
Yellow Submarine

(Leading numbers and spaces removed)

I've got an Action created that says this:

Regular Express: "TITLE": "^\s*\d+\s*-\s*" -> ""

When I run the Action (whether on 1 or many files) it does not work at all.

This USED to work on my older XP machine but has never working on Win 7 for me. I'm running the very latest version of Mp3Tag (2.55a)

I've attached a screen shot of my actions

Any ideas?

As far as I can see there are not leading spaces in front the number. So the "^\s" is probably too much.
Also you use in this pattern a "\s*-\s*" which is " - ": where do you find that in "01 A Day in The Life"? I can see no hyphen.

I would use "Replace with regular expression"
^\d\d (.*)
