I just updated my AIR SDK to 1.5.3 from 1.5.2 and when I attempt to build my application I get the following error:
Unable to locate specified base class 'mx.core.WindowedApplication' for component class 'MyApp'. I've done some searching and not come up with anything. Fortunately I backed up my Flex SDK folder before doing this update (using 3.4). Reverting back to that allows the app to compile. Unfortunately, my signing certificate just expired and though I have a new one I need to use AIR 1.5.3 to migrate properly. Does anyone have any thoughts on what my problem is?
