Hey Simon,
That's a shame. It's odd that following the instructions doesn't seem to achieve the desired result.
Yes I use Brackets as i find it very easy to use, and it has the colour swatch which I found helpful.
I'll try and do a screencast of the process for you to follow and post it here. If it doesn't work I can only think there's a difference in your installation which would need investigating. Greg Pell is on your timezone and others are US timezone which might make it easier.
Good luck!
Helen
