Can't load second swf

Hi,

I'm new to articulate and I am making my first presentation. So my plan was to make some swf files in flash and then insert them in my powerpoint presentation.

I did my first swf file with an action at the end so it moves to the next slide:

_level0.ArtAPI.PlaySlideNum(2);

As i have read to do so, im publishing my swf files in flash 6 AS 1, then inserting them in my powerpoint with those options:

"Advance to next slide :" > "When user clicks next"
"Synchronization" > "Movie plays independently form slide" 

The problem is, when i publish the presentation it loads correctly the first slide with my swf on it and when it finishes it moves to the second slide BUT it doesn't play my second swf. However, if I hit on the forward and backward buttons of the player controls it actually change from the first slide to the second and plays my two swf without problems.

I am really getting mad at this so any help will be most appreciated
