When opening a .b4a file, a popup window appears stating "Error accessing the follwoing files, Choose.balFile Already Exists" and same for other .bal files (e.g. Main.bal): I have 3 activities, each with its own .bal file. When I click OK & Compile & Run the app, it objects to the line Activity.LoadLayout("Main") stating "Activity BALayout: Layout not available".
The Files tab (on the IDE) shows the .bal files.
What's the cause of the "Already Exists" error?
