I've had Lion 10.7.4 recently installed, and Dreamweaver CS6 now crashes when I try to open an existing index.html file that opened fine in Snow Leopard 10.6.8. Nothing has changed on this file.
You can test if it's a corrupt file or something funky in the code by opening the page in Firefox or Safari, then copying the source and pasting it into a new file in DW (save as index2.html). If it's a code problem, DW will crash. If everything looks right, you can do a Save As to replace the old index.html that may have corrupted for any number of reasons.
Thank you. I did what you said and it froze again. It does it with all the pages on the site. I'm wondering if it has anything to do with any of the .js scripts on the site. Below is the code from the index page.

what you can do to test from here is (make sure to be in code view only, on a new copy/paste page) comment out all of your java scripts. Add <!-- in front of the js in the code and add --> after each .js reference. That will make the browser and hopefully DW skip all of your scripts. The page "should" then be viewable in the design mode without crashing (it will likely be very broken looking). Then take out the <!-- and --> one at a time while paying attention to which code you are re-activating. Eventually it will crash again, but it will tell you which script is killing DW. Then someone with a little more Javascript-Fu will be able to help you out.
Google fonts?
It could be the way Lion handles requests from Dreamweaver for network access - or even it could be something related to font integrity checking on Lion. There is/was a security vulnerability regarding malformed fonts being used as an attack vector to execute arbitrary code on a targeted machine and I'm pretty sure Apple released a security update to address this. Perhaps the way Apple verify's the font is okay to load into RAM doesn't play well with Dreamweaver.
That's just a guess though. You could look through your logs with Console.app and see if anything stands out.
I am runniing Creative Cloud on Lion 10.7.4 and Dreamweaver hangs on start up. I've tried uninstalling and reinstalling and it acts the same way. I'm not trying to open an existing file, just launching the program. I think that there is some bug in the latest update. If anyone from Adobe is listening, look into this.
