I needed to update air to 3.6 for use with Flash Builder. I overlayed the newest Air SDK with a copy of Flex 4.6.0. Now, when I try to create any new Flex projects, none of the core swc files will load. For example this error: "unable to load SWC ._asc-support.swc"
Why can't it load these files? They are listed in the project explorer as expected.
