I can not read ActionScript 1 in Flash CS6?

[TaaDaa]

Hello I was sent an .fla file by a potential client to see if I could convert the animation to HTML5. As luck would have it - I do still have CS6 on my computer - but when I  hit F9, in the opened file, I see this:  Warning: in this unregistered version, no Action Script will be generated while exporting the FLA. Please purchase the full version to get Action Script at http://www.sothink.com/product/flashdecompiler/index.htm.

Questions:

1.  Can I work on ActionScript 1 in Flash CS6 (I know I used to be able to?!?? I do not see ANY ActionScript only that warning)?

2.  If not, is there anyway to see/work with ActionScript 1?

3. What is the meaning of that warning?

4.  Does anyone have any links on best practices for converting an ActionScript 1 & 2 fla file to HTML5?!! 

Thank you!!

I very much doubt an Adobe product error message is directing users to sothink dot com.

I added a picture. I didn't unstand it either....

someone decompiled a swf in order to create that fla

Oooooooooh NICE!! That would explain it!!

Also just as a helpful tip... You CAN download a free (1 month) copy and get to the actionscript in their SoThink Decompiler.

yes, you can work with as1 in flash cs6.

Please check out the picture I just added to my post.  You will notice that I highlighted the frame with (a) ActionScript in it and truly that warning came up. I remember being able to code in AS1 and AS2 in CS6?!?!?!
