Movieclip not playing

[Extinct]

I have this small problem which I can not figure out.

I made a Movieclip which fades between 3 words (textfields). The 3 words are each on a seperate layers and I tween every layer in an out (alpha tween) with a slight shift in time. When I play it in the library it work perfectly.
However, when I drag an instance of the movieclip to the first and only frame on the scene and test it, it doesn't work. It just displays the 3 words on top of each other.

Anyone?

On your timeline make 2 layers:
1)actions
2)my_mc

On the 1st layer put an stop() action an on the second one drag your movie. If still doesn't work post a link to your .fla file or send it to: dragos.bocai@rdsct.ro Regards,
Dragos.

Actually it's a bit more complicated. I have several layers in my scene, including actions. and on the first fram of the actions layer I dynamically attach movieclips (not the fading text movie), but I tried to use the fading text mc in new fla and got the same result.
Anyway, I'll try to add stop() at the end of my code and see if it helps.

It's been some time since I worked on this and I have the same problem again. I solved it last time myself but I don't remember how.
Now I only changed 1 character of code and it didn't work anymore.
I can play the movieclip in the library but the instances won't play.
Please help me...
