Campaign Notes with Vista

[Gordons HQ]

Hi Everyone,
I can't read the Campaign Notes with Vista. When I try it just says widows no longer supports the help file in this version of windows.
I have seen the supposed fix for it on the HPS site but I can't get anything to work.
There it directs you to Microsoft site to install a fix, that's a minefield in itself, I've tried installing their fix and still get the same result, nothing.
I was wondering if anyone else knows how to fix this and can talk me through it, or even if there is a fix for this.
Cheers,
Gordon
