I am not sure if IDE is even the correct terminology to be honest. I am still a nub developer and prefer to stick mainly with php although javascript and action script are not uncommon. (html and css of course) But here is the deal.

I learned what I do know about Web Development with Dreamweaver CS4. Just on my own time with what I have learned on the internet, it's kind of like my hobby. (I work a lot). The company wants there license back and says that I will no longer be able to use the software. Can some one point me in the right direction towards a comparable if not equal open source editor?

Any Suggestions would be greatly appreciated.
