Hey i have this movie symbol in the library, i drag it to the stage, try to test movie and it doesnt appear!!
Its a simple movie with a few .jpg inside and a motion tween. There is no code anywhere on the main movie that as any reference to this symbol and instance. I checked all properties.
i copy the symbol to another project, drag it to stage and it shows properly on test!!!
Plz somebody help me i have been trying to fix this for almost 2 hours. 
UPDATE: It seems it becomes visible if i have only 5 or less jpg… how do i fix this?? its a rolling display of pictures…
it figures. you all are masters on coding and stuff, but can’t help on a problem with paranormal causes. maybe i should call the x-files…
I’d suggest that you start a new x-file…it appears that your fla may have become corrupted in some way because, as you said, you can copy the symbol to a new fla and it works. So copy that particular symbol, and all other assets, from your Library into a new project and start over. Sometimes that’s not a bad thing as you will invariably discover more efficient ways of structuring your fla when you do this.
One other thing you can try before you start over - copy all your assets to a new project and save it. Then copy the offending movie clip symbol from the new project into the one that doesn’t work. When prompted, replace the existing movie clip symbol and see if that makes a difference.
Finally, on the subject of paranormal causes - we definitely lack clairvoyancy skills. Without actually seeing an fla, it’s virtually impossible to know what has caused the problem…some dodgy code, a flash bug, poor movieclip design…or even the Cigarette Smoking Man.
