Very strange @jalpher, I’m really sorry about that.
Would it be possible to share your project file with us to see if we can figure out what’s going on? If your comfortable with that, you can send it to firstname.lastname@example.org. We will jump on it as soon as we see it :).
To start with the easy stuff: What OS are you using?
Windows 10, if not kept up to date, gets grumpy when dealing with Adobe Air. We have seen a couple patches that break Adobe Air functions, only to be quickly patched a few days later.
Also, if you are on Windows, would you mind heading over to https://get.adobe.com/air/ and grabbing the newest version - just to be sure we are up-to-date?
I’m sorry again for the trouble. We will do our best to figure out what is up.
