In the 2014.1 update, the libraries for C+ extensibility are no longer working. These are libraries that we have used Since Dreamweaver MX when it was still Macromedia.
We have tried contacting Adobe about the problem but have not gotten a response.
We are trying to find a way to work around it and will have dot releases available as soon as possible.
This is really not a case of Adobe changing how something is done, it is that core componants that we have used relliably for quite some time (DW MX dates back to 2002) are no lonbger functioning.
