dw mx 2004 files won't load in cs3

My friend designed a website using dw mx 2004. He has sent me the files but I when I try to load them onto my dw cs3 access is denied, so I am having compatibility issues. Is there a way dw mx 2004 can be loaded onto cs3? If not, do I need to get 2004 or what are my best options? Thanks a bunch.

I don't personally use DW, but do the files you're trying to open have either a .htm(l), .css, .js, .php or .asp extension?

i.e. if it's not a file unique to Dreamweaver, but a web-related file, then there's either an issue with your CS3 or an issue with the file permissions.

What *exactly* does the error say?

(If it is a DW-specific file, ignore everything I just said!)

I have read your article and have one question to ask, would you pls Post your MSN to me?

I personally have never had a problem opening any web related file in any dreamweaver, but i suppose it could cause a conflict if you have used some of their own features...
