I have Flash Builder 4.5 installed, and I am joining a project mid point (project is in SVN) that someone has already set up. Unfortunately he uses FDT4. I am trying to figure out how to open/import/use this project in Flash Builder, but I am having no luck. I got to the point where I was able to import the project, but am unabee to debug or run it. I have tried to update any paths/settings in the project properties, but nothing seems to work. Has anyone successfully done this? Any thoughts on how? The other thing I need to be sure of is that no changes I make will mess up the project settings for the original developer who uses FDT when I committ my changes back to SVN.
