I have tried searching the forums and help for a solution to the error message I am receiving, but have been unable to find a scenario the same as mine. After I have exported my FW project to HTML and CSS and have opened it in Dreamweaver, when I click on the FW icon in DW to edit it, a few problems occur. First, it takes a long time to open (compared to the amount of time it takes for my other CS5 applications to open. Secondly, an error message pops up saying "File could not open. An internal error occured." However, the file eventually does open and I am able to edit it. Any solutions on how to fix the problem?
