Less than 24 hours bumps on topics are not a correct way to act in these forums. That is bad in this way.
As zenox said, be patient and do some search on your own as well.
Also simply asking the same question over and over again is not the best way to get answers. If you did not get some in the original topic, perhaps you are just asking the wrong question.
1. You don't give enough informations. According to your other previous topics on the subject you were already answered on the subject, and still are asking the very same thing.
Either post a project with a detailed and precise explanation of what you are doing, what you expect the code to be doing and what you are actually experiencing.
As far as I can tell, using the "On end of layout" and "On start of layout" events should do the trick. If not, post the capx of your project so it can be reviewed, don't just create duplicate threads of the very same "question".
2. You should actually ask this question directly in the topic for this plugin.
3. This blog article contains links to tutorials on how to export using the actually supported method with Construct 2. Be sure to also implement and respect the performance and memory usage tips on your application.
In preview you should also be able to check for errors in your browser which will give directions and clues on what is going wrong.
