Photoshop CS4 CRASH on using Flash Panel from SDK examples

Hi!

I'm trying to create a panel using Flex, flash and javascript. But I cannot finish tutorials - they all CRASH photoshop with almost the same code in init() function when using CSXSInterface.** functions.
When I comment those ones, it's all ok (the script loses functionality, but panels don't crash).

For example this code

CSXSInterface.instance.evalScript("PhotoshopRegisterEvent", charToInteger("setd").toString());

crashes my Photoshop CS4.

What's wrong? AIR logger doesn' say anything.

Thank you!
