Well you look like you have done the right thing
Here is a working example from my wampmanager.conf
editor = "c:/program files/notepad++/notepad++.exe"
So maybe the problem is with Crimson Editor! Its not one I have ever used, I had a quick look and it does seem a little old, last amended in 2008!?
If in doubt, try installing Notepad++, its also free and it does work and is probably as good if not better than Crimson.
