Welcome to WebmasterWorld Guest from 184.108.40.206
But you need access to the server on which the site is located. If the creator signed the company up with an external host and walked off with the account details and/or passwords then you have a problem.
If the hosting isn't done in-house then you will definitely need some FTP software to up/down load.
Other issues may arise depending on what the creator did or failed to do.
I can't find anything in CS3 that will let me import code from a url.
Thanks for all of your input and suggestions!
