Adobe Air + Box2D.swc = TypeError: Error #1009 // New way to handle .swc files in Flash for iOS Apps?

Question

Hi,
I need your help please - I have to update one of my iOS Apps. In this App I use Box2d for a simple maze game (it's an app for kids). When I publish & test this game on my Mac it works fine. I can drag my Hero (fish) through this Maze and all collision detections, gravity etc. work perfect.
When I test it on my iPad it doesn't work. The device debugger shows this error message:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Line 31: loader = new CLibInit();
I guess "CLibInit" should come from the .swc file.
The thing is:
I didn't change anything in this maze game - it seems this has to do something with the new Flash and/or Adobe Air version. Box2D.swc file is included:
It always worked like this - and it works when testing it on my Mac - but it is no longer working on my current system.
So I started my Mac from an older system (10.9.5 on an external HD) and published the App from Flash CS6 and Adobe Air 13.0 - then it suddenly worked on my iPad as before. I was able to tap an the fish and drag it arround.
The same project / app published from my current OS X 10.10 + Flash CC 2014 + Adobe Air 15.0.0.302 is not working. I always receive this Error Message - I can not drag the fish - nothing happens. And I have no idea why this happens and what else I could do. I searched the whole day for a solution but didn't find anything.
So did anything change by the way Flash and/or Air handles .swc files? Is there an other way to include: import cmodule.Box2D.* / CLibInit ?
Please - if anyone has a clue - please let me know!!
Best regards

Update:
There is also an Android Version of this App. I just published and tested a new version of it on my kindle fire & Samsung Galaxy Tab 2. On both Tablets the maze works perfect. I'm able to drag the fish around etc.
Then I published this Android Version for iOS and tested it on my iPad. Again I'm getting the Error message:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

...and the fish is stuck - I can't drag it - nothing happens. So this error only occurs when I publish the App for iOS - as an .ipa. Did anything change in the way Air handles .swc files?
I'm totally confused
If anybody has an idea what I could try - PLEASE LET ME KNOW!!
