Facebook-actionscript-api - project dont want to compile

Hi,
I try to add some fb functionality to the website using the facebook-actionscript-api
Whenever I add this line:

  • private var fbSession:FacebookSessionUtil; - the project dont want to compile. I’ve used it in other project and it did worked. The difference is that this time Im using Flash Player 9 instead of 10. I cant change it to the v10 because in this case project dont want to compile also.

To make it clear, project finally gets compiled but the only thing I see is background from project and thats it. No errors are thrown and the compilation time is very long ~about 5 minutes.

So I wonder if its problem with FP version or something different. Maybe you know if there is a version for FP9? I cant find any info on that in facebook-actionscript-api project website.
